LOVO has been really useful in our social media production. It has allowed us to generate voice-overs and character dialogue for some of our output. We use LOVO as part of our script writing process to preview copy and depending on the project, deliver the recording. Being able to audition from a great range of voices and delivery styles, with a script in realtime, is very advantageous and helps us achieve client approval so much quicker.

For Spiral we had the challenge of having voice tapes that were somewhat gender neutral and to sound nothing like any other of the Saw franchise films. I came up with the idea of an A.I. style of voice. Going through LOVO’s library of voices we came across a female voice that spoke the words very well for clarity. When we pitched and slowed down the wav files, we got exactly what we needed. Clear, neutral, and weird! Thanks LOVO!

I used LOVO to create the spoken intro and the outro. I was really amazed at how easy it was to use it. You just basically enter the sentences you want to speak, you select the speaker that you want to use, and you can already download the audio file. Thanks a lot for the service!

We used LOVO's Speech Synthesis and TTS technologies to create a special product feature for our Toonation creators. Each creator recorded a short script to clone their voice, which they could use to create content on their own, and also allow their fans to use when the fans made donations to them in their channels. Both the creators and the fans loved the freshness of this new feature and of its quality. The key factor was that LOVO was able to capture each creator's tone, pronunciation, character, and the general speaking habits to really encapsulate their persona.

Closed Captioning vs Subtitles: Understanding the Differences

All you need to know about video captions

What are subtitles?

Subtitles are written representations of spoken dialogue, narration, or other audio elements in a video, film, or multimedia content. They usually appear at the bottom of the screen and provide a written transcription of the audio in the same language or a translated form.

Why do you need AI captioning?

Video Captions have multiple benefits:

1. Accessibility:they make the content accessible to individuals who are deaf or hard of hearing, which is crucial to ensure that they can comprehend and follow the content without any hindrance.
2. Multilingual Support: By providing captions in various languages, a video caption generator allows a wider global audience to comprehend the content.
3. Improved Comprehension: The presence of video captions can help improve content comprehension, especially when dealing with accents, dialects, or complex dialogue. Additionally, captions can be helpful in noisy or distracting environments, like crowded public spaces, allowing viewers to follow the conversation more easily.
4. Environmental Considerations: Subtitles allow viewers to follow the dialogue in noisy or distracting environments, such as crowded public spaces.
5. SEO: AI captioning can be a powerful tool to enhance the discoverability of video content by assisting search engines to index and rank it effectively.

To put it briefly, using a video caption generator and automatically generating captions will improve the approachability and functionality of multimedia content, thereby making it more comprehensive, user-friendly, and appealing to a wide range of viewers.

What is the difference between static and animated auto generated captions?

Including subtitles in video content is crucial as it enables the audience to receive information through text. Two types of captions that are commonly used are static and animated video captions.

Captions classified as static remain fixed at the bottom of the screen throughout the entire duration of the video playback. These captions are commonly used in traditional media forms like movies and documentaries. The static nature of these provides consistency and simplicity to the viewer, providing a stable reference point for the text.

In contrast to static captions, animated captions incorporate dynamic effects to the text that change or move during video playback. These captions are commonly seen in creative, artistic, or youth-oriented videos as they add an engaging visual element to the text.

How does AI captioning work?

Automatic subtitles, commonly referred to as closed captioning, are generated through the use of speech recognition technology and natural language processing.

The process begins with an audio or video file containing spoken content, which is uploaded to a video caption generator and then converted into written text using an automatic speech recognition (ASR) system.

Automatic Speech Recognition (ASR) technology is capable of recognizing individual words and generating a written transcript of the spoken content. To enhance the accuracy of the generated text, it may undergo Natural Language Processing (NLP), which can correct errors, identify the context, format the text to make it more readable, and add the necessary punctuation.

To synchronize text with the audio, timestamps are added to each line of text. Once the text is finalized and timestamped, it can be formatted and added to the video file or provided as a separate subtitle file. The most commonly used subtitle file format is SRT.

These subtitles generated by an auto caption generator are typically presented at the lower part of the screen and can be personalized in terms of font, size, and design.

What is an SRT file?

The SubRip Subtitle file, commonly known as an SRT file, is a popular file format used for saving subtitles or closed captions in video content. These files are in a simple text format that can be easily read by humans and consist of timed lines of text. They provide information about when particular content should be displayed on the screen while watching a video.

SRT files have become a popular choice for adding subtitles or closed captions to videos, as they are compatible with various video players and editing software. Moreover, they are widely used for translating subtitles into different languages and ensuring proper timing for accessibility. If you use Genny as a video caption generator, you have the option to download them as an SRT file or hardcode them into your video.

What are hardcode captions?

Burned-in subtitles, also called hardcoded subtitles or open captions, are a kind of subtitle that is added to the video image during the encoding process and cannot be removed or personalized by the viewer. These video captions are always visible at the bottom of the video frame.

Captions play a vital role in videos, especially in cases where understanding the content is crucial, such as foreign language films or videos with critical dialogue. They are a permanent and indispensable component of the video.

When should you use AI captioning?

Adding captions to content by using an auto caption generator can improve its accessibility, engagement, and comprehension. There are various reasons why people choose to do so, but the most prevalent ones include:

✅ AccessibilityCaptions are crucial for individuals who experience hearing difficulties or are completely deaf.
✅ Global AudiencesMaking use of subtitles generated by a video caption generator can help to make content available to people from around the world and those who come from diverse linguistic backgrounds.
✅ ClarityEnhancing the transparency of verbal communication and assisting the audience to comprehend the content in noisy surroundings are some of the benefits provided by them.
✅ SEOSubtitles can boost video content's search engine optimization (SEO) and help ensure compliance with regulations. Additionally, using an auto caption generator can improve viewer engagement and retention while making the content accessible to a wider audience.


Overall, subtitles are a valuable addition to many forms of audiovisual media and should be used based on the specific goals of the content and the needs of the target audience.

How do I make my own captions with an auto caption generator?

Creating subtitles in Genny's video caption generator can be done in a few simple steps:

1. Upload your video (mp4) or script (.docx or .txt file) to Genny.
2. Click on the "Subtitle" icon.
3. Select between auto generated subtitles, manual, or upload an SRT file.
4. Select your font, color, and style (animated or static.)

And that's it! Your subtitles will be ready to download from the Auto Subtitle Generator as a separate SRT file or as hardcode subtitles in your video.

What is the difference between closed captions, open captions, and subtitles?

Open captions, closed captions, and subtitles are different methods of displaying text on a video screen to convey spoken content. While they all serve the same purpose, they differ in their characteristics and functionality.

Open CaptionsOpen captions are permanently embedded into the video and cannot be turned off or customized by the viewer. They are always visible and displayed every time the video is played. Open captions are useful when the content creator wants to ensure that the captions are always present and cannot be altered. They are commonly used when captions are essential for understanding the content.
Closed CaptionsClosed captions can be turned on or off by the viewer, giving them control over whether they see the captions. They are stored in separate files that can be added to or removed from a video during playback. Closed captions are often used to comply with legal requirements for accessibility, making content accessible to individuals with hearing impairments. These are the most commonly used type of captions for television broadcasts, online streaming, and educational videos.
SubtitlesSubtitles are primarily used to provide translations of spoken content or to enhance comprehension for viewers who might have difficulty understanding the spoken language due to accents, dialects, or background noise. Like closed captions, subtitles can often be turned on or off by the viewer. Subtitles are commonly used to translate content into different languages, making content accessible to a global audience. With the use of an Auto Subtitle Generator, the process of creating subtitles becomes a lot faster.

In summary, open captions are always visible and cannot be turned off. Closed captions are customizable and often used for accessibility, while subtitles are used mainly for translations or to enhance comprehension and can be turned on or off by the viewer.
