7 Best AI Voice Generators You Must Try Now


<p>The ability to generate sounds, including speech, has been crucial in multiple industries such as entertainment. With the advent of deep learning, the popularity of deep generative models grew, especially in TTA, the task of creating audio based on text input. </p>



<p>Taking inspiration from Stable Diffusion, a <a href="https://arxiv.org/abs/2301.12503">paper</a> by <a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Liu%2C+H">Haohe Liu</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Chen%2C+Z">Zehua Chen</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Yuan%2C+Y">Yi Yuan</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Mei%2C+X">Xinhao Mei</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Liu%2C+X">Xubo Liu</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Mandic%2C+D">Danilo Mandic</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Wang%2C+W">Wenwu Wang</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Plumbley%2C+M+D">Mark D. Plumbley</a> proposes AudioLDM: a TTA generation model which uses latent diffusion models. A notable aspect of this model is the use of CLAP for latent extraction, allowing AudioLDM to learn audio representation without cross-modal relationships to achieve both efficiency and quality.</p>



<p>We have summarized the paper below, but here are some key points that are important to note:</p>



<ol>
<li><strong>AudioLDM uses CLAP for latent extraction</strong>. This enables audio embeddings containing text information to be obtained without having to compute cross-modal dependencies, leading to a higher computational efficiency.</li>



<li>In tandem with the above advantage, <strong>the use of CLAP results in quality improvement</strong> with the model prior generation now only coming from audio (refer to the forward process of the diffusion model in the paper).</li>



<li>The <strong>model and its latent variable tractability allow for competitive results</strong> in zero-shot text-guided audio style transfer, inpainting/super-resolution, showing its applicability beyond TTA.</li>
</ol>

<h3 class="wp-block-heading"><strong>1. Contrastive Language-Audio Pretraining</strong></h3>



<p>Inspired by the recent success of CLIP in text-to-image generation, Audio LDM takes advantage of CLAP to aid its TTA synthesis (marked as Contrastive objective in the figure above). The model leverages a text encoder and an audio encoder to extract embeddings from the two sources, that are used as inputs to CLAP. This allows for the extraction of an audio embedding that contains text information.</p>



<h3 class="wp-block-heading"><strong>2. Conditional Latent Diffusion Models</strong></h3>



<p>With the use of the CLAP, AudioLDM now extracts audio embedding Ex from audio input x and text embedding Ey from text input y. The latent diffusion model is then trained to match its distribution, p(z0|Ey) (with parameter theta) with the true conditional data distribution q(z0|Ey), with z0 being the latent of the audio sample x.</p>



<p>The diffusion model essentially achieves the following during its training/sampling phase:</p>



<ul>
<li>During training, z0 synthesis is achieved with audio embedding Ex used for noise estimation.</li>



<li>During sampling, the audio input is absent and z0 synthesis is guided with predicted noise from text embedding Ey.</li>
</ul>



<p>In other words, the diffusion model is conditioned by audio embeddings during training, and text embeddings during sampling. CFG (Classifier Free Guidance) is applied on the diffusion model, with modifications to its noise estimation including application of a guidance scale, determining the effect of conditioning information.</p>



<h3 class="wp-block-heading"><strong>3. Encoder/Decoder</strong></h3>



<p>VAE&#8217;s encoder is used to compress the audio into its latent space, and its decoder reconstructs the mel-spectrogram from z0. The model is trained with reconstruction, adversarial, and Gaussian constraint loss. The reconstructed mel-spectrogram is finally fed into a vocoder for audio generation (HiFI-GAN used for AudioLDM).</p>



<h2 class="wp-block-heading"><strong>Text-Guided Audio Manipulation</strong></h2>



<p>The authors show that the model not only excels in TTA, but also displays significant performance in text-guided audio manipulation as well as audio inpainting/super-resolution. This involves a slight change to the model&#8217;s inference flow, as shown below.</p>

<p>Firstly, text-guided audio manipulation is attained by exploiting the nature of diffusion process. Via a shallow reverse process, latent variable z0 can be computed from an &#8220;earlier&#8221; latent at diffusion step n0, where n0&lt;N and is computed from forward process equation. The starting point of the the reverse process, n0, controls the manipulation results. As n0 approaches N (gaussian noise), information from original source audio will be gradually lost and the model will behave like the conventional TTA. Note that the latent at n0 can be obtained from the source audio to be modified with text guidance using the learned forward diffusion process. Additionally, by exposing the model to latent representation of a partial audio (expressed in the above diagram with z superscript ob), the model can also be used for inpainting/audio super-resolution, generating the missing audio based on the given audio latent. This is specifically attained by applying observation masks during reverse diffusion process, which denotes generation and observation part, indicating which section of the audio must be generated from text embedding conditioning while retaining original audio.</p>



<h2 class="wp-block-heading"><strong>Conclusion</strong></h2>



<p>While the idea of generative AI with latent diffusion is not new, the model&#8217;s capability in zero-shot text-guided audio style transfer is interesting. With appropriate training data, the shallow reverse diffusion process could be used to embed emotion and add effects to already synthesized audio. As an example, with a sample audio of a narrating voice that has been already generated from TTS, the user could input a guiding text, such as “An angry man shouting with sirens buzzing in the background.”, to modify the original and match the guidance.</p>

AudioLDM: Text-to-Audio Generation with Latent Diffusion Models

SmoothQuant: Accurate and Efficient Post-Training Quantization for Large Language Models


<p>Transformers are proven to perform well not only in language-related tasks, but also in vision. Despite their performance however, transformer-based models are extremely difficult to train on small datasets, especially for vision-related tasks.</p>



<p>To address this problem, a <a href="https://arxiv.org/abs/2305.09828">paper</a> written by <a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Trockman%2C+A">Asher Trockman</a>,&nbsp;<a href="https://arxiv.org/search/cs?searchtype=author&amp;query=Kolter%2C+J+Z">J. Zico Kolter</a>  proposes mimetic initialization. As its name suggests, the self-attention weights of the transformers are initialized in a way that mimics those of their trained counterparts, allowing for a faster convergence</p>



<p>This is a summary of the paper with our key takeaways and conclusion.</p>



<h2 class="wp-block-heading"><strong>Observation of Transformer Weights</strong></h2>



<p>As discussed above, mimetic initialization aims to replicate the pre-trained self-attention transformers&#8217; weights. Naturally, the first step is to observe the weight patterns. The weights are defined as follows: query and key weights with d x k dimension, and value and projection weights, with d x d dimension (considered to be full rank). d is the dimension of the transformers, k is the head dimension, i.e. d divided by number of heads. Given those weights, for inputs X (n x d) with additive positional embeddings P (n x d), attention map is defined as follows.</p>



<figure class="wp-block-image size-full"><img data-attachment-id="4654" data-permalink="https://lovoai.wpcomstaging.com/post/mimetic-initialization-of-self-attention-layers/equation-4/" data-orig-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-4.png" data-orig-size="279,54" data-comments-opened="0" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="equation-4" data-image-description="" data-image-caption="" data-medium-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-4.png" data-large-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-4.png" decoding="async" loading="lazy" width="279" height="54" src="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-4.png" alt="" class="wp-image-4654"/></figure>



<p>After formally defining the weights involved in self-attention, ViT-Tiny is dissected for analysis as shown below. It is possible to note a common pattern, in which a positive diagonal is formed from the product of query and key weights. Similarly, the product of value and projection weights hold a negative diagonal.</p>



<figure class="wp-block-image size-full is-resized"><img data-attachment-id="4410" data-permalink="https://lovoai.wpcomstaging.com/post/mimetic-initialization-of-self-attention-layers/figure-1/" data-orig-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/08/figure-1.png" data-orig-size="806,337" data-comments-opened="0" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="figure-1" data-image-description="" data-image-caption="" data-medium-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/08/figure-1.png" data-large-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/08/figure-1.png" decoding="async" loading="lazy" src="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/08/figure-1.png" alt="" class="wp-image-4410" style="width:840px;height:337px" width="840" height="337"/><figcaption class="wp-element-caption">Figure 1.

<p>For language models on the other hand, a similar pattern is noted, but this time query-key product and value-projection product are now negative and positive, respectively. However, note that value-projection product gradually becomes positive for deeper layers.</p>

<h2 class="wp-block-heading"><strong>Initialization</strong></h2>



<p>Given the above observations, a simple initialization can be made to satisfy diagonality (below initializations are for ViT transformers). Given by the fact that random normal matrix is approximately orthogonal (given Z with dimension d x k and Z ~ N(0,I/k), product of Z and its transpose is equal to the identity matrix), the following can be defined.</p>



<figure class="wp-block-image size-full"><img data-attachment-id="4655" data-permalink="https://lovoai.wpcomstaging.com/post/mimetic-initialization-of-self-attention-layers/equation-1-1/" data-orig-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-1-1.png" data-orig-size="214,49" data-comments-opened="0" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="equation-1-1" data-image-description="" data-image-caption="" data-medium-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-1-1.png" data-large-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-1-1.png" decoding="async" loading="lazy" width="214" height="49" src="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-1-1.png" alt="" class="wp-image-4655"/></figure>



<p>Note that the normal matrix is scaled by the transformer head dimension to maintain unit average diagonal magnitude. For negative diagonal in the case of value-projection product, the sign of projection weight can be simply inverted to obtain the below equation.</p>



<figure class="wp-block-image size-full"><img data-attachment-id="4656" data-permalink="https://lovoai.wpcomstaging.com/post/mimetic-initialization-of-self-attention-layers/equation-2-1/" data-orig-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-2-1.png" data-orig-size="362,49" data-comments-opened="0" data-image-meta="{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}" data-image-title="equation-2-1" data-image-description="" data-image-caption="" data-medium-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-2-1.png" data-large-file="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-2-1.png" decoding="async" loading="lazy" width="362" height="49" src="https://lovoai.wpcomstaging.com/wp-content/uploads/2023/09/equation-2-1.png" alt="" class="wp-image-4656"/></figure>



<p>However, such initialization does not provide control on how much accentuation should be put on the diagonal. Thus, the equation can be further modified into the following.</p>

<p>For the above equations,  Z ~ N(0,I/d) and alpha, beta values lie in [0,1]. The parameters explicitly determine the strength of the diagonal. With such modification, the attention map can be re-written.</p>

<p>From this form of the attention map equation, it is visible that the type of positional embedding can affect mimetic initialization and thus its performance.</p>



<h2 class="wp-block-heading"><strong>Results</strong></h2>



<p>The novel initialization method was shown to work consistently on relatively small dataset (in comparison to JFT-300M), such as Tiny ImageNet, CIFAR-100, and SVHN, showing an improvement in classification accuracy by 5.63, 6.39, and 0.39 respectively. It is noteworthy that the use of sinusoidal position embeddings is necessary, showcasing its role in mimetic initialization (as also indicated from attention map equation). The paper attributes the success of this method to its mathematical similarity to other techniques used to improve ViT trainings. The below image shows the similarity of attention maps obtained from ViT under various pretraining and initialization conditions. Notice the similarity between the mimetic-initialized model&#8217;s attention maps to those of ImageNet and CIFAR-10 pretrained models.</p>

<p>Mimetic initialization was shown to also work with language models. While the improvements in the metrics are not as obvious as those in vision models, results from both small scale and medium scale tasks display a drop in their perplexity and BPC (bits-per-character, similar concept to cross entropy for language models).</p>

<h2 class="wp-block-heading"><strong>Conclusion</strong></h2>



<p>The key takeaways for this paper are as follows:</p>



<ol>
<li>Visual transformers are known for their poor performance when trained on small datasets. Mimetic initialization offers a solution to the problem by mimicking the self-attention transformer weight patterns, offering faster convergence for smaller datasets.</li>



<li>The method does not require any additional training nor modifications to the original model. It is also analytically found that the initialization shares similar properties as existing training aiding methods for transformers.</li>



<li>The initialization does not only show significant improvements for vision models, but also for language models.</li>
</ol>



<p>The results of this paper can be used for faster training of current TTS models which actively use transformers, as this method not only showed results on visual data but also on sequential data (and thus, applicable to speech). Specifically, this could be beneficial when training new architectures on smaller datasets for which a pre-trained model does not exist.<br><br>Link: <a href="https://arxiv.org/abs/2305.09828">https://arxiv.org/abs/2305.09828</a></p>

<p>Are you wondering how to create your own AI voice via AI voice cloning? Voice cloning is the process of creating a digital copy of your voice (or someone else’s), and was initially done using voice recognition software.&nbsp;</p>



<p>Today, we have more advanced artificial intelligence (AI) technology that makes voice cloning easier. It’s also more accessible thanks to the emergence of AI-powered platforms, apps, and tools designed specifically for AI voice generation.</p>



<p>Below we’ll dive into everything you need to know about creating your own AI voice and more.</p>



<h2 class="wp-block-heading">What is AI voice cloning?</h2>



<p>AI voice cloning, also referred to as voice synthesis or voice mimicry, is a technology based on text-to-speech (TTS). TTS AI is exactly what it sounds like — technology that enables your text to be converted into speech, and it’s been around for much longer than most people realize.&nbsp;</p>



<p>Of course, with AI TTS has come a long way from sounding like a robot that lacks emotion, tone, and inflection. This is especially true for AI voice generation and cloning, as it involves the use of voice data to learn and analyze the unique vocal characteristics of the individual voice being cloned.</p>



<p>Put simply, AI voice cloning is the technology that allows you to create a digital copy of your voice or someone else’s voice to use later with your text of choice. What’s more, voice cloning includes:</p>



<ul>
<li>Speech patterns</li>



<li>Accents</li>



<li>Inflection points</li>



<li>Emotion</li>



<li>Breathing patterns</li>



<li>Varying tones</li>
</ul>



<h3 class="wp-block-heading">How does AI voice cloning work?</h3>



<p>AI voice cloning uses special cloning models created to utilize techniques known as <a href="https://www.ibm.com/topics/deep-learning">deep learning</a>. Deep learning is a type of artificial intelligence that actually teaches computers to process data in a way that essentially imitates the way the human brain works when gaining certain types of knowledge.&nbsp;</p>



<p>The most common type of model used for AI voice generators and cloning is known as a <a href="https://www.ibm.com/topics/recurrent-neural-networks">recurrent neural network</a> (RNN). RNNs deal with sequential data, which is how human speech is categorized under TTS. Once the RNN model in the AI voice cloning tool of your choice has been adequately trained for the voice you want, it will be able to generate speech from your text in that specific voice.&nbsp;</p>



<h3 class="wp-block-heading">What are the benefits of AI voice cloning?</h3>



<p>While AI voice cloning has become somewhat of a controversial topic, it comes with plenty of benefits for those who intend to use it for content creation, music, video shorts, films, and more.&nbsp;</p>



<p>The benefits of AI voice cloning include:</p>



<ul>
<li>You can choose the exact voice you want to use, whether it’s yours, a friend’s, or a celebrity&#8217;s (if available).</li>



<li>Your voice clone will sound much more human than traditional TTS applications. In fact, it’ll sound exactly like the voice you’re using as the RNN will actually <em>learn</em> how to mimic the voice in question.</li>



<li>It’s much more cost effective than having to hire vocalists or voice actors.</li>



<li>Many AI voice generators that enable cloning also enable customization, which means you can tweak the voice’s digital copy to your liking.</li>
</ul>



<p>Important to note here are the ethical considerations of AI voice cloning. Currently, there isn’t any legislation regarding using someone else’s voice. However, using someone else’s voice without their consent — especially if that voice is used to say things they wouldn’t approve of — could land you in some hot water.</p>



<p>It should be noted that laws revolving around using someone else’s voice without their consent may crop up in the near future. Therefore, it’s important to only use AI voice cloning as ethically as possible and keep an eye out for any developments in the space.</p>

AI Voice Cloning 101: How Can I Create My Own AI Voice?


<p>Generative AI has come a long way in an incredibly short amount of time. It’s transformed from a novelty into a fully-fledged tool that makes life easier for those with limited resources. Generative AI can create text, images, audio, and even video based on your specifications, providing a lifeline for small businesses needing content and marketing materials.</p>



<p>With generative AI being so new, there&#8217;s quite a learning curve for those getting started. Within this guide, we’re going to look at just what generative AI is, how it works, how you can use it, and how to navigate its various challenges.&nbsp;</p>



<h2 class="wp-block-heading"><strong>What is generative AI?</strong></h2>



<p>Put simply, generative AI is a type of artificial intelligence that essentially acts like a digital artist that can make all kinds of content on demand. Despite its very recent rise in popularity, generative AI is not a new idea. In fact, the first chatbot was created by <a href="https://www.theguardian.com/technology/2023/jul/25/joseph-weizenbaum-inventor-eliza-chatbot-turned-against-artificial-intelligence-ai#:~:text=In%201966%2C%20an%20MIT,the%20%E2%80%9Cpsychotherapist%E2%80%9D%20would%20reply.">MIT Professor Joseph Weizenbaum in 1966!</a>&nbsp;</p>



<p>Things really started to heat up in 2014, when research scientist Ian Goodfellow developed <a href="https://www.ibm.com/blogs/systems/generative-adversarial-network-technology-ai-goes-mainstream/">generative adversarial networks</a> (GANs). This technology pits two neural networks against each other, resulting in incredibly realistic content. From this moment on, generative AI stopped being a pipe dream and started being a serious tool for rapid content generation. Let’s take a quick look at what it can do.</p>



<h3 class="wp-block-heading"><strong>Text</strong></h3>



<p>Generative AI models like GPT-3 and its successors can generate coherent, contextually relevant text. For instance, they can write articles, compose poetry, or even create code snippets. Here&#8217;s an example of a generated text using the prompt <em>“Write a short sentence describing a sunset”</em>:</p>



<p>“As the sun dipped below the rugged peaks, it bathed the serene lake in a gentle, golden radiance.&#8221;</p>



<p>That’s great stuff, and you would be hard-pushed to think it wasn’t written by a human.</p>



<h3 class="wp-block-heading"><strong>Images</strong></h3>



<p>GANs have resulted in AI image generation becoming incredibly realistic. GANs combined with machine learning and other new technologies have made AI image generation simple with dazzling results. In some cases, even an AI-generated photograph can be indistinguishable from a real-life photograph.&nbsp;&nbsp;&nbsp;</p>



<h3 class="wp-block-heading"><strong>Voice</strong></h3>



<p>Ever heard a voice from a computer or a voice assistant that sounds almost like a real person? That&#8217;s thanks to AI too. <a href="https://lovo.ai/">AI voice generation</a> has also improved exponentially in the past couple of years. In many cases, AI voices can recreate a human voice to an indistinguishable level.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Video</strong></h3>



<p>AI video generation is still finding its feet. Some platforms are able to create realistic video content, others will provide video with that signature generative feel. Video editing with AI however can work very well, using pre-captured video and editing it together to create engaging video content. As AI image generation continues to improve, we expect AI video generation will quickly follow in its footsteps.</p>



<h2 class="wp-block-heading"><strong>How does generative AI work?</strong></h2>



<p>Generative AI is often seen as the successor to traditional AI, but they’re actually just two different approaches to artificial intelligence.&nbsp;&nbsp;</p>



<p>Traditional AI, often referred to as rule-based or classical AI, is an older paradigm of artificial intelligence that relies on explicitly programmed rules and logic to perform specific tasks. In traditional AI systems, human experts create rules and algorithms that will process data and make decisions. They’re purpose-built to serve specific situations and do not possess the ability to learn from data or adapt autonomously.</p>



<p>On the other hand, generative AI is a more modern and advanced approach that falls under the umbrella of <a href="https://www.ibm.com/topics/machine-learning">machine learning</a>. Generative AI systems, such as generative neural networks, use large datasets to learn patterns and generate content autonomously. These systems can create new, creative content, whether it&#8217;s text, images, audio, or even videos, without explicit programming or rule-based instructions.&nbsp;</p>



<p>Until recent years, machine learning was used in a limited capacity. It would be trained to recognize and classify patterns within the content it was given. For example, the insurance industry uses machine learning to recognize common signs of potential fraud by feeding data from previous cases. The insurers could then use their newly trained AI to quickly check over the details of new cases and compare them against thousands of other cases to see how they lined up.&nbsp;</p>



<p>Machine learning has made generative AI into a powerful tool through self-supervised learning. This type of machine learning requires a substantial amount of data to be fed into the AI, which it will then use to generate predictions. After all, generative AI is still looking for patterns and predicting the most likely outcome based on your prompt. You could even argue that it’s simply statistics.&nbsp;</p>



<p>With enough data being fed to an AI, the resulting generated content is simply the most statistically probable outcome. Say you ask ChatGPT a question, the AI will scour its database to identify the most likely answer. This is why information is occasionally incorrect, as it relies on pre-fed data rather than looking through the entire internet for the most up-to-date information. The more data fed into an AI, the more accurate its predictions can become.&nbsp;</p>



<p>Users of generative AI have been working just as hard as developers in creating ways to improve the output of AI models. Prompt engineering has become the “secret sauce” to making generative AI feel human, to the point where companies are creating new roles and <a href="https://www.forbes.com/sites/jodiecook/2023/07/12/ai-prompt-engineers-earn-300k-salaries-heres-how-to-learn-the-skill-for-free/?sh=3abfcf129d4a">paying $300k salaries</a>.</p>



<p>Prompt engineering itself is quite simple — it tasks you with finding the perfect prompts that will guide the AI towards the correct result. This has wide-ranging applications across all generative AI platforms, with audio, image, text, and video requiring prompts to give you the result you’re looking for.&nbsp;</p>



<p>Getting prompt engineering right can take time. It’s often an iterative process that requires refinement, and the same prompt can have a different impact depending on the AI platform you’re using. There are, of course, applications that will automate prompts on your behalf. However, much like the AI itself, automated prompt generation is going to give you generic results that may not be exactly what you’re looking for.</p>



<h2 class="wp-block-heading"><strong>Benefits of generative AI</strong></h2>



<p>Generative AI has a huge range of benefits for a wide range of industries. It has become a crucial tool for many businesses for the following reasons.</p>



<h3 class="wp-block-heading"><strong>Get the content you need, fast</strong></h3>



<p>Even the best content creators can’t deny that AI gets the job done faster. Human creators can spend hours, even days crafting the perfect content for your business. However, we’re not always afforded the luxury of time. Generative AI can create content in minutes, or even seconds when it comes to short-form content.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Save money and resources</strong></h3>



<p>Like time, money is finite. Small businesses especially are not able to allocate huge budgets to content-based marketing. Using AI with a prompt engineer allows a business to create the content they need without putting themselves out of pocket.</p>



<h3 class="wp-block-heading"><strong>Easier ideation</strong></h3>



<p>With so much data to pull from, generative AI is an incredibly useful tool when it comes to ideation. Text-based generative AI platforms can bring fresh perspectives to the table to uncover ideas your team may not have imagined.&nbsp;</p>



<p>You can use generative AI for a number of ideation purposes, including:</p>



<ul>
<li>Concept generation</li>



<li>Concept expansion</li>



<li>Content inspiration</li>



<li>Prototyping and visualization</li>



<li>Scenario generation&nbsp;</li>
</ul>



<p>On top of this, generative AI can also identify market gaps by showing you what is already being done. This will help you to expand your business’ horizons and enter new areas that your competitors have not touched yet.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Engaging and informative summaries</strong></h3>



<p>Generative AI is already working from a huge collection of data and is constantly learning which parts of that data are most important. This makes it an amazing tool when it comes to summarizing, as it can quickly identify key points within your content and generate summaries that touch upon every single one in your summary.</p>



<h3 class="wp-block-heading"><strong>Make sense of large data sets</strong></h3>



<p>Generative AI can generate summaries or representative samples of large datasets. This is particularly helpful for providing quick insights into the dataset&#8217;s content without the need to process the entire dataset exhaustively.</p>



<p>It can also be used to generate visual representations of data, such as charts, graphs, or diagrams, to help analysts and researchers gain insights from large datasets more easily.</p>



<h3 class="wp-block-heading"><strong>Speed up existing systems</strong></h3>



<p>Generative AI can enhance the efficiency of slow systems by accelerating processes and improving resource utilization through tasks such as data compression, optimization, and predictive modeling. This helps businesses to streamline operations, reduce computational overhead, and enhance overall system performance.</p>



<h2 class="wp-block-heading"><strong>Challenges of generative AI</strong></h2>



<p>Generative AI has a significant amount of naysayers. This makes it a tricky topic of conversation, especially for those who make a living creating content and are worried that AI is being introduced to replace creative careers. Let’s look at some of the key issues that come with generative AI.</p>



<h3 class="wp-block-heading"><strong>Cybersecurity</strong></h3>



<p>Generative AI has become a valuable tool for coders looking to automate common, often tedious tasks. The problem here is that text-generation AI platforms now have a huge amount of code on their databases. This can then be used by unscrupulous individuals to create code with malicious intent, even if they don’t know how to write code themselves.</p>



<h3 class="wp-block-heading"><strong>Poor quality and misinformation</strong></h3>



<p>Social media has a big misinformation problem right now and there are some who worry generative AI is fueling the fire. Anyone can create large amounts of low-quality, potentially misleading content and post it to the internet without any oversight. This can quickly lead to AI-generated content being presented as fact, with potentially damaging consequences.</p>



<p>We saw this happen very quickly with Meta’s “Galactica” AI. The tech giant trained Galactica using 48 million scientific papers, aiming to help “organize science”. Unfortunately, they had to shut down the AI after just 2 days. Rather than giving factual snippets, the AI would generate nonsensical responses that would contradict itself. In <a href="https://www.cnet.com/science/meta-trained-an-ai-on-48-million-science-papers-it-was-shut-down-after-two-days/#:~:text=Galactica%20also%20struggled%20to%20perform%20kindergarten%20math.%20It%20provided%20error%2Driddled%20answers%2C%20incorrectly%20suggesting%20that%20one%20plus%20two%20doesn%27t%20equal%203">some cases</a>, it couldn’t even answer simple math questions correctly.</p>



<h3 class="wp-block-heading"><strong>Copyright</strong></h3>



<p>One of the biggest issues people are highlighting is how many AI companies are flagrantly ignoring copyright laws. Generative AI models are built by trawling the internet and grabbing content for its database. This is a fully automated process that doesn’t leave much room for copyright compliance.&nbsp;</p>



<p>While it can be incredibly difficult to see just what copyrighted content has been taken by generative AI platforms, a <a href="https://www.theverge.com/2023/8/19/23838458/ai-generated-art-no-copyright-district-court">landmark ruling in the US</a> has set a precedent when it comes to copyrighting AI-generated work. A piece of art was rejected by the US Copyright Office multiple times, leading Stephen Thaler to seek help from the US District Court. In the ruling, Judge Beryl A. Howell stated that the AI-generated piece could not be copyrighted due to the lack of “human authorship”.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Big players</strong></h2>



<p>Let’s wrap up by quickly looking at the key names in the generative AI market right now.</p>

<p>Adding a voice over to a video is a great way to improve audience understanding and engagement. Whether you are making a corporate video or adding narration to a screen recording, a voice over will make your content much richer. The development of voice over software has made it so simple to add voice over to video. Let’s look at when you should add a voice over to a video and exactly how you do it.</p>



<h2 class="wp-block-heading"><strong>When Should You Add Voice Over to Video?</strong></h2>



<p>You should add a voice over to a video when you want to clarify what people are seeing on screen. If the video is a movie or a TV show, then it has sufficient context that a voice over is not needed, although narrators are sometimes used to add context to a story.</p>



<p>Voice overs work great when you are giving people information. They are instrumental when you are&nbsp;<a href="https://lovo.ai/post/7-ways-to-use-voice-over-marketing-for-business-growth">creating marketing materials</a> like explainer videos. <a href="https://lovoai.wpcomstaging.com/post/how-to-create-an-explainer-video-in-5-simple-steps/">Explainer videos</a> essentially perform as more entertaining PowerPoint presentations. The video acts as the slide visuals, and the voice over acts as the presenter.&nbsp;</p>



<p>Voice over not only increases engagement, but also improves accessibility. It makes content more inclusive for people who have visual impairments or who learn audibly. If you use voice over software like LOVO, you can also easily add multiple languages to a video, increasing its global accessibility.</p>



<h2 class="wp-block-heading"><strong>7 Steps for Adding Voice Over to Your Video Content</strong></h2>



<p>Adding voice over to your&nbsp;<a href="https://lovo.ai/tutorials/getting-started/creating-a-video">video content</a> is easy, but there are a few key elements that you need to consider. Follow these seven simple steps to start creating professional videos.</p>



<h3 class="wp-block-heading"><strong>Step 1. Choose the Right Voice Over Script</strong></h3>



<p>Writing your voice over script can be a daunting task, and can be the most challenging part of this process if you choose to do it yourself.&nbsp;</p>



<p>When writing your script, keep your audience at the front of your mind. Think about what they need to know, what they want to hear, and how they like to hear it. The tone of your script should be a reflection of your audience.&nbsp;</p>



<p>Ensure you keep the script concise and with a natural flow. You want to have a clear message but don’t be afraid to tell a story. To keep your audience&#8217;s attention, your video needs to be entertaining as well as informative. Finally, always end with a call to action (CTA). Give your audience something to do once your video is over.&nbsp;</p>



<p>If writing the script yourself is too daunting, why not have your voice over software write it for you?&nbsp;<a href="https://lovo.ai/ai-writer">LOVO’s AI writer</a> can prepare a professional script to your specifications in moments.</p>



<h3 class="wp-block-heading"><strong>Step 2. Select the Perfect Voice Software Solution</strong></h3>



<p>Choose a&nbsp;<a href="https://lovo.ai/post/the-best-ai-video-editors">voice over software</a> that makes it easy to start&nbsp;<a href="https://lovo.ai/tutorials/getting-started/create-a-project">your first project</a>. When finding the software that&#8217;s right for you, consider:&nbsp;</p>



<ul>
<li>Which voice over tools you will want to utilize when adding the audio file to your video</li>



<li>Whether you want to use more traditional&nbsp;<a href="https://lovo.ai/text-to-speech">text-to-speech</a>&nbsp;or an AI-created voice clone</li>



<li>Which languages you want your audio to be translated into</li>
</ul>



<p>All of these considerations should help you choose the perfect voice over software for your project.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Step 3. Select a Voice and Language</strong></h3>



<p>The range of voices that you can choose from is vast. You can specify factors, including the gender, ethnicity, and age of the voice you choose. If you want to get a truly <a href="https://lovoai.wpcomstaging.com/post/tips-tricks-improving-your-diy-custom-voice/">custom voice</a>, you can use voice cloning technology. This allows you to reproduce the voice of a human and create unlimited audio files using that voice. Voice cloning recreates the nuances of a human voice, not just the accent, pitch, and tone.&nbsp;</p>



<p>The best <a href="https://lovo.ai/">AI voice generators</a> also allow you to choose from a range of languages. This speech feature is a massive advantage if you make a video targeted toward a more international market. Producing multiple versions of your voice over in different languages is easy to do, but each new audio must be created separately. Ensure you match the script&#8217;s language with the language of the voice you choose.</p>



<h3 class="wp-block-heading"><strong>Step 4. Type or Paste Your Script</strong></h3>



<p>Before you add your script to the speech tool, ensure there are no errors or typos. It can also be helpful to segment the script into manageable sections with clear headings. At this stage, you can also specify any pronunciation notes. Depending on the software you use, you can highlight words for emphasis and specify the overall tone of the AI voice over.</p>



<h3 class="wp-block-heading"><strong>Step 5. Export the Voiceover File</strong></h3>



<p>When you are ready to export the voice over recording to an audio file, simply choose the file type and quality. You can also adjust the volume level of the voice recording and, depending on your software, the playback speed.</p>



<p>Name the file something appropriate and save it in a secure location. If you have saved it in high quality, you may also want to consider compressing the file to save on storage. Now, you are ready to add your voice over to the video.</p>



<h3 class="wp-block-heading"><strong>Step 6. Fine-Tune the Voice Over Recording and Video Synchronization</strong></h3>



<p>This is when you open the&nbsp;<a href="https://lovo.ai/online-video-editor">video editor</a> to synchronize the voice to the video timeline. Ensure that your volume levels remain consistent throughout the video playback and that the voice over does not overshadow any crucial sounds that are already present in the video.</p>



<h3 class="wp-block-heading"><strong>Step 7. Enhance the Impact of Voice Over With Background Music</strong></h3>



<p>If you want to make your video even more engaging, consider adding background music. You can use one song throughout or add several audio tracks in various parts of your video. Choose an <a href="https://lovoai.wpcomstaging.com/post/audio-branding/">audio track that is on brand</a> and doesn’t distract from the information being given in the voice over. Ensure that each audio level is appropriate so they meld well together.</p>



<p>When choosing your music, it is important to consider copyright laws. You must use royalty-free music or obtain permission to use the music.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Leverage Realistic AI Voices That Captivate Your Audience</strong></h2>



<p><a href="https://lovo.ai/text-to-speech">LOVO</a> offers a full range of features to help you in your video production. Script writing, AI voice creation, and an inbuilt video editor are all available. To captivate audiences, you can also generate AI voice clones with real human emotion.

5 Best Text-to-Speech Software for Inclusive Marketing


<p>Not all of us have been gifted with the talent of an artist. It takes <em>years</em> to hone the skills of sketching, drawing, painting, photography, or graphic design. But thanks to breakthroughs in artificial intelligence technology, you won’t need to.&nbsp;</p>



<p>AI <a href="https://lovoai.wpcomstaging.com/post/the-best-ai-art-generators/">art generators</a> can produce endless masterpieces in all kinds of styles. If you can imagine it, an art generator can bring it to life. From paintings of giant pink elephants wearing a top hat in space to a realistic portrait of a person in a photographic style — anything is possible! All you have to do is type in what you’d like to see, and the AI tool will create it in seconds.&nbsp;</p>



<p>With so many artistic possibilities, knowing exactly how to prompt art <a href="%view_link%">generators to get the image</a> you want can be hard.&nbsp;</p>



<p>We’ve pulled together a handy <a href="https://lovoai.wpcomstaging.com/post/can-you-sell-ai-generated-art-a-comprehensive-guide/">guide on how to write good AI art</a> prompts that generate the perfect images and some prompt ideas for you to try out.&nbsp;</p>



<h2 class="wp-block-heading"><strong>How Do AI Art Generators Work?</strong></h2>



<p>To know how to craft a good prompt, it’s a good idea to familiarize yourself with how AI art generators actually work.</p>



<p>These tools rely on complex algorithms and neural networks that have been trained on vast amounts of existing art. They use this training to generate brand-new images based on the prompts that users write.&nbsp;</p>



<p>Once they receive the prompt, the AI processes the text and attempts to create an image that matches the description as closely as possible.&nbsp;</p>



<p>It’s important to note that despite the incredible art and imagery they can generate, these AI tools don’t <em>really </em>understand visuals in the same way humans do. That’s why prompts need to be descriptive, with clear and specific instructions.&nbsp;</p>



<p>The prompts can include the subject of the art, as well as art styles, colors, descriptions, key elements, and more.&nbsp;</p>



<p>For example, asking for a ‘cute’ painting of an animal wouldn’t be very helpful. It would be better to be specific about what kind of animal, its age, fur color, size, where it is, and what style of painting you want.&nbsp;</p>



<h2 class="wp-block-heading"><strong>How To Write AI Art Prompts</strong></h2>



<p>Writing a successful AI art prompt requires a good balance of creativity and clarity. Here are some tips to help you write effective prompts that will create captivating AI-generated art.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Define The Style</strong></h3>



<p>AI art generators can emulate a wide range of artistic forms and styles. Be sure to clearly state the style you have in mind, whether it&#8217;s photorealistic, impressionistic, abstract, and so on. You can even specify the medium of the art, such as whether it’s an oil painting, drawn in crayon, sketched in pencil, etc.&nbsp;</p>



<p>Here’s a list of specific art forms you can explore:</p>



<ul>
<li>Photography</li>



<li>Painting</li>



<li>Illustration</li>



<li>Digital art</li>



<li>Film stills</li>



<li>Sculpture</li>



<li>Collage</li>



<li>Street art</li>



<li>Textile art</li>
</ul>



<h3 class="wp-block-heading"><strong>Include Lots Of Detail</strong></h3>



<p>As we touched on above, detail is critical when prompting AI art generators. The more detail you provide, the better the AI can understand and translate it into the visuals you’re looking for. Be specific about not only the subject matter but also the context, emotions, colors, and any other relevant details.</p>



<p>Here’s a list of details you could include:</p>



<ul>
<li>Framing</li>



<li>Level of realism</li>



<li>Lighting</li>



<li>Color scheme</li>



<li>The background</li>



<li>Any other background details or objects to include</li>
</ul>



<h3 class="wp-block-heading"><strong>Imitate Famous Artists</strong></h3>



<p>If you’d like your image to be reminiscent of a famous artist, you can ask the AI art generator to produce it in their style. For example, you could prompt it to produce art “in the style of” renowned artists like Van Gogh, Frida Kahlo, Rembrandt, Francisco Goya, Andy Warhol, or anyone else you can think of.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Explore Art Eras</strong></h3>



<p>You could prompt your AI to create art reminiscent of different periods in art history. Whether you&#8217;re interested in Medieval, Renaissance, Abstract, or Impressionism, AI can generate pieces that capture the essence of that era. For instance, playing around with modern concepts painted in a historical context could be interesting.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Use A Structure</strong></h3>



<p>Organize your prompts with a structured format. This might include specifying the subject, providing detailed descriptors, and indicating the desired style. You could experiment with different structures to see what gives you good results, then apply that same structure to new prompts.&nbsp;</p>



<h2 class="wp-block-heading"><strong>5 AI Art Prompt Examples To Try</strong></h2>



<p>Here’s some inspiration for AI art prompts to play around with to help you familiarize yourself with these innovative tools.&nbsp;</p>



<h3 class="wp-block-heading"><strong>A Majestic Fantasy Landscape</strong></h3>



<p>A landscape with mountains and waterfalls in the style of J.R.R. Tolkien&#8217;s illustrations.</p>



<h3 class="wp-block-heading"><strong>A Headshot</strong></h3>



<p>A headshot photo of a smiling blonde girl wearing a cap.</p>



<h3 class="wp-block-heading"><strong>Modern Cyberpunk Cityscape</strong></h3>



<p>A futuristic urban scene with skyscrapers and vehicles, with people in the streets, in the style of cyberpunk artist Syd Mead.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Serene Monet Garden</strong></h3>



<p>A garden scene in the style of Claude Monet, with water lilies, a pond, and dappled sunlight.&nbsp;</p>

How To Write AI Art Prompts Like A Pro


<p>Video is one of the most consumed forms of content on the internet, thanks to platforms like YouTube and TikTok. Marketing teams have quickly adapted to this shift, with <a href="https://www.wyzowl.com/video-marketing-statistics/#stat-1-1">91% of businesses</a> using video as a marketing tool in 2023. Unfortunately, this also presents a problem for some businesses. Video creation is a lengthy process. Finding the right voice for your content, and then recording your audio, can feel like more trouble than it’s worth. Could voice cloning AI be the answer?<br><br>We have already dug into what voice cloning does <a href="https://lovo.ai/post/synthetic-voice-and-voice-cloning">in a previous post</a>. So, in this post, we will lay out a quick AI voice cloning tutorial to help your business use this unique technology.</p>



<h2 class="wp-block-heading"><strong>6 Ways To Use Voice Cloning In Business</strong></h2>



<p>There are plenty of potential uses for AI voice cloning, especially as the technology advances. Here are just a few ways you can use voice cloning in your business.</p>



<h3 class="wp-block-heading"><strong>Create Personalized Voiceovers</strong></h3>



<p>AI voice cloning lets you speak your truth even if you don’t have the time or equipment to record the audio yourself. You can write up a script that touches on everything you need to get across and let the voice cloning AI speak for you. This is perfect for creating advertising, social media, and even training content for your business.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Increase Accessibility</strong></h3>



<p>Offering an audio version of your text-based content helps those with visual impairments connect with your business. Rather than struggling with walls of text and incredibly basic, robotic text-to-speech programs, those users will be able to hear your content as it should sound. This increase in accessibility will help build meaningful connections with users you might not have been able to reach out to without a voice cloning AI.</p>



<h3 class="wp-block-heading"><strong>For Customer Service Chatbots Or Virtual Assistants</strong></h3>



<p>Virtual assistants are becoming a big part of many people’s lives. AI voice cloning allows you to make a virtual assistant and even chatbots seem more human by giving them a “real” voice. This also will help build confidence in your brand, as users are quickly picking up on that impersonal “default” AI voice.</p>



<h3 class="wp-block-heading"><strong>Improve IVR Systems</strong></h3>



<p>A bad interactive voice response (IVR) system can quickly frustrate customers, who often just want to speak to a human on the other end of the line. Voice cloning AI helps reduce the annoyance of IVR systems by giving a realistic voice and a conversational feel to the IVR process. AI <a href="https://lovoai.wpcomstaging.com/post/how-to-effectively-use-ai-tone-of-voice-in-advertising/">voice cloning also allows you to create an IVR system that matches the tone</a> of your business with friendly, personalized messages and interactions.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Include Personalized Voice Messages In Email Marketing Campaigns</strong></h3>



<p>Voice cloning AI can give your email campaigns a little extra life. Rather than just plain text and the hope that you come across correctly, you can use your AI voice to bring your words to life. This will help get your brand’s tone across with little room for confusion. It will also increase engagement, as those who hit that play button will likely make time to explore your business further.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Create Podcasts Or Audiobooks In Your Cloned Voice</strong></h3>



<p>Content marketing is an all-encompassing discipline that goes above and beyond the usual blog posts and email blasts. Again, voice cloning can help bring your words to life by turning your written content into a podcast or audiobook. This brings a higher level of engagement compared to written content alone. The added time spent listening to your content will create a deeper connection between the listener and your business.</p>



<p>All of the above ideas can help strengthen your brand’s identity and improve the customer experience by using a clone of your voice to personally promote your business.</p>



<h2 class="wp-block-heading"><strong>LOVO AI Voice Cloning Tutorial</strong></h2>



<p>While it may seem daunting at first, getting to grips with voice cloning is quick and simple. You can create highly engaging content that accurately represents your brand’s tone through online voice cloning with <a href="https://genny.lovo.ai/signup">Genny</a> from Lovo AI. Here’s how:</p>



<ul>
<li>Open Genny and create a new project</li>



<li>Select &#8220;Voice Cloning&#8221; from the menu on the left side of the screen</li>



<li>Click &#8220;Create a Voice Clone&#8221;</li>



<li>Either upload your own audio or record your voice. Genny will give you written prompts to read out if you are recording your own voice.</li>



<li>Once everything is recorded, you can then choose if you&#8217;d like your voice to be &#8220;more stable&#8221; or &#8220;more expressive&#8221;. This dictates how accurate the voice clone sounds versus how emotive it sounds.</li>



<li>Click &#8220;Create voice&#8221;</li>
</ul>



<p>Once those steps have been completed, you can then preview your voice and see how it sounds. If you’re not sure about your new AI voice, you have a range of options to make it right for you. You can re-record your audio, add more clips or change the stability/expressive ratio until you get the result you’re looking for.</p>



<p>Once you&#8217;re happy with your AI voice cloning, simply click &#8220;use this voice&#8221; to save it. You’ll be asked to fill in some key identifying information, such as what you want to name the voice, and the age, gender, accent, and style of the voice. This will make it simpler to find your voice again if you capture more down the line.&nbsp;</p>



<p>You&#8217;ll also need to confirm that you have the right and permission to upload and duplicate these voice samples, and you won&#8217;t use it for anything unlawful, deceitful, or detrimental.&nbsp;</p>



<p>And that&#8217;s it! Your new cloned voice shows up as another voice option in Genny, and you can use it in all your projects.&nbsp;</p>
