An AI voice is a voice that is created by artificial intelligence, whether from cloning a human voice already in existence or synthetically made. The last couple of years have seen tremendous leaps and jumps in both the quality of the AI voices and the widespread applications of these voices.

If you aren’t sure why anyone would use AI voices instead of real human voices, or vice versa, check out this guide [How to save 90% of your budget creating voiceover content] that compares the two. If you are already familiar with AI voices and are looking for options, I’ll go through some of the best AI voice applications and services you can start using to get cranking with your content.

How, or Where, Do You Use AI Voices?

Before we delve into the list, let me take a moment to explain how the AI voices are actually used for the folks who are new.

The most common way is via Text-to-Speech [TTS]. This technology actually dates back to the 1960s, to the days of Noriko Umeda of the Electrotechnical Laboratory and physicist John Larry Kelly Jr who developed the first versions of computer-based speech synthesis. The user would input text, choose a voice of their choice, and the engine would convert the inputted text into a speech using the chosen voice. It can be used in a variety of settings: YouTube, Podcast, Audiobooks, Ads, Product Explainers, On-Hold Messages, IoT Devices, Navigations, Apps, Chatbots, Corporate LMS, Education, Movies, Games, and much more.

Another approach is voice conversion, or speech-to-speech technology. This is where you choose the desired output voice, submit a recording with your voice, and get the converted audio in return. This increases flexibility for cases where typing or uploading text is difficult. In the simplest sense, you can think of this as Snapchat voice filter or “monster voice filter”, but instead of merely distorting the sound, you actually get to choose human-like voices. High-quality real-time voice conversion is something that’s yet being worked on – 2023 might be the year that we see this come out in the market (keep your eyes peeled here!)

Alrighty, shall we now dive into the top 10 companies providing AI Voices?
