Just a couple years back, if you explained Text-to-Speech to someone, 9 out of 10 you would hear the response “why would anyone use that?” Now, the dialogue isn’t about whether to use it or not, but whether which ones are better than the rest. From those that offer subpar voices to the ones that offer human-like sophistication, we have found 7 essential qualities every effective Text to Speech software must possess.

1. Voice Quality

The primary aspect that differentiates any text to speech software from its competition is the quality of its voices.

There are many facets to consider when we say “quality”:

  • expressivity
  • clarity
  • intonation
  • punctuation
  • pronunciation
  • styles and emotions to fit the context
  • human-like imperfection
  • over-all fidelity

text to speech software should deliver high-quality voices that mimic the style, prosody, and emotion of human speech. Through contextual awareness, the AI voice should also be able to pause, breathe, and enunciate in all the right places as necessary.

2. Variety

There should be a bevy of options for gender, age, language/accent, and use case. Such diversity is what makes a TTS tool so powerful: it’s like having hundreds of voice actors at your fingertips.

Regardless of whether you are only serving a local community or the global population, having the ability to produce content in multiple languages, accents, and dialects help you tailor your offerings and overcome any cultural or language barriers. Customizing the voice based on your audience, content, and the brand significantly amplifies business opportunities for you.

Additionally, having an array of emotions and styles to choose from grants you the flexibility to utilize that same voice in different contexts, unlocking creative potential for you and your business.

3. User Interface

User Interface (UI) can make or break a sound product, but unfortunately, there is no “one size fits all”. Some prefer a simpler look, while others prefer a soft, pastel tone, and then there are those who need the most professional design to get their work done. The one experience that should run through various UI is that it should be easy to use. With just a few clicks, users must be able to convert text to speech and create compelling realistic voiceovers for their projects.

In other words, the platform should be user-friendly, intuitive, and doesn’t require an extensive training.

4. Control

Any solid TTS platform should empower you with mastery over your final output.

This can be as basic as modifying speed of the readings, inserting pauses in between sentences, or adding emphasis to certain words. A more advanced tool would allow you to edit the pronunciations of words so you can get the proper pronunciations for foreign words, acronyms, and special nouns. The most robust products will let you adjust the pitches on phoneme-levels for that granular control.

5. Import & Export

Another essential feature of an easy-to-use Text-to-Speech service is the ability to seamlessly import and export files in multiple formats. Importing and exporting files is a key part of any content work, so user should be able to either copy-and-paste text to an editor or import text files in different formats directly. At the same time, there should be an option to export the final audio or video file in various formats.

An added advantage would be allowing users to add media files such as images, videos, music, and presentations to the final voiceover and sync them to create the perfect digital content.

6. Add-Ons

You may start with the notion that you’ll simply turn text into a voice and be done with it. However, as you get more acquainted with TTS and AI voice tools, you’ll soon have a few “I wish I could do this” pop-up in your head.

Best Text-to-Speech products should support you with an arsenal of add-ons, such as a library of music, non-verbal interjections, and sound effects (SFX). Your productivity and creativity will increase exponentially if you don’t have to search the web for background music or sound effects (i.e.; fire burning, car honking, or bomb blasting). Having non-verbal interjections like coughs, uhms, and “wows” make your voiceovers that much more human and realistic.

A handful of top TTS platforms lets you clone your voice or create a custom branded for your business as well. You can create as many content as you want without ever having to record yourself, allow your team or colleagues to create content on your behalf, or come up with a special voice that your customers can remember you by.

7. Future

One of the most overlooked but a nonetheless important aspect to consider when deciding on any content creation tool should be its life expectancy.

By that, we mean:

  1. Will this product exist a couple years, or even a few months, down the line?
  2. Will there be updates and upgrades?
  3. Will there be someone to help me when I’m stuck?

You don’t want to get situated with a platform, have your routine set up around it, and then realize it’s gone the next moment, or the founding team’s deserted it. Make sure you choose one that’s alive and kicking so you can provide them feedback and help it improve – so it can help you.
