What’s the Best Text to Speech AI Software? Here Are 10 Audio Samples for You to See for Yourself

Affiliate Disclosure: Some of the products and services mentioned on this website pay affiliate commissions to the creators at no cost to you. Thank you for your support!

The 2020s have become the age of AI. It seems as if we're seeing new and exciting AI powered programs released daily.

Some of the most exciting developments have come in the AI voice generation space. There are dozens of options that all promise to be the best AI text to speech generator (or at least the best free AI voice generator available). 

But which are actually worth using?

Well, you can only truly find through testing! So that's exactly what we've done. 

We purchased each of the 10 tools for this demo and ran them through the same audio script test. We also dug deep into each of them to see what they do well, where they fall short, and what sets them apart. 

My purchases!

Just a few of the programs I signed up for one night while doing tests for you guys! No stone was left unturned.

I promise you, no one has actually bought each of these plans and tested them to get the same holistic comparison like we did for you in this article!

Quick Note...


This article is focused on using AI text to voice transcription to create content. We aren't reviewing tools like Speechify that are used to read PDFs or other text out loud for you as a productivity hack.

What We're Looking for in AI TTS 

There are a number of features that we're looking for.

  • Realism. The less robotic sounding, the better. We want smooth pacing, correct inflections and tones that match the subject matter. 
  • Audio editing correcting. We want to be able to adjust speed of speech and correct pieces of audio we don't like. Ideally, we can quickly regenerate clips that we don't like. Some tools offered a lot in this area, while others keep users closer to the original outputs. 
  • Voice creation. Some softwares were able to generate completely original AI voices that aren't used by anyone but the creator. It's very cool if you want something that is extremely personal for your brand. 
  • Voice options. How many voices are there to choose from and how many different "actors" are available? We want to know which genders, ages, accents, and styles we have available as well as things like special reading styles. Some have things like "narrator," "whispering," or "promotional" voice styles. 
  • Price. Pricing can vary dramatically. Some tools are pay-as-you-go, while others are on a subscription billing program. We know that many creators just want something quick and free, so we paid special attention to the best AI text to voice generators with free plans. Most of the tools had some form of free plans, but most didn't come with a commercial license or the ability to download the files until you paid. 
  • Output limits. We wanted to know how much text we can input and generate at once per payment cycle.
  • Commercial rights. This is a no brainer, but we need to legally be able to use our audio however we want. Do NOT download and use any audio unless you're certain that you have commercial rights to use it. 
  • Voice cloning. Also known as "deep fakes," this feature lets you create versions of your own voice or the voices of others. This is not available on each of these tools, and the output quality varies as well. 
  • Stand out features. We wanted to know if there were any features that were exclusive to certain tools. There were, and we made note of them. 

How We Tested

We ran the same text to speech requests through each tool, so we could compare the results side by side. 

AI Test Script

We wanted to test different pronunciations, pacing, and inflections. 

We used a sentence that is difficult for AI to create.

"The quick brown fox jumped over the lazy dog." 

We also created variations of this to test exclamations and questions.

"Did the quick brown fox jump over the lazy dog?" 

And "Wow! The quick brown fox jumped over the lazy dog! Oh my gosh!"

Next, we tested to see if the tools could get abbreviations correct. We gave it the following sentence: “R.S.V.P. for my A.I. webinar A.S.A.P.”

Finally, we wanted to test some words that are commonly mispronounced. With the help of ChatGPT, we compiled a sentence that includes 10 of these difficult words. The sentence is “The mischievous entrepreneur, an epitome of rural quinoa farming, cultivated a chimera of caramel anemones near a nuclear plant, sparking hyperbolic rumors.”

Other Testing Notes

A couple of other notes about how we tested...

#1 We chose male voices with English text to English-speaking voiceovers and American accents

English was by far the most common language supported by all tools we found. 

We did our best to create a quick pricing and feature overview of each of the 10 programs we included in this test, which we provide. 

We found that the male and female versions were typically the same quality. For brevity, we had to choose one, and we went with male and a standard American accent. 

#2 We didn't edit the outputs

We wanted to see which tools provided the best output without a bunch of work. We make notes about tools that can provide better output with a little of tinkering.

That feature is important since no automatic generation has been perfect.  

#3 All exports were done in .wav files if possible and with the highest quality possible. 

Using .wav is standard for adding audio to videos. The most common use for text to voice seems to be for video voiceovers, so we felt this was the best choice. A couple of tools only exported in .MP3.

What Do We Recommend?

As you can likely tell from the fact that all the audio in these experiments was hosted with it, we use and recommend Play.ht to creators who are very serious about the quality of their voice overs. 

However, it isn't the cheapest option.

FAQs

What Is AI Text to Speech?

Text to speech has been around since as early as 1968 but the technology has advanced significantly since then.

The latest AI text-to-speech technology can do much more than simply say the words we tell it to. Now, it can recognize speech patterns, interpret them and create coherent responses. 

It is not the same as regular text to speech tools because it can create its own creative answers from the input we provide it.

AI technology uses something called phonemes to form words and sentences, and it relies on intonation, accentuation, and pronunciation to create coherent and meaningful conversations in tones and accents that seem close to human.

AI voice text-to-speech uses machine learning technology to learn and adapt according to new data it receives. As the database of real voice actors expands, AI text-to-speech technology can create new and unique speech that is unique to the brand that uses it. 

What Are Some Real World AI Text to Speech Uses?

There are many commercial uses of AI text-to-voice software, some of which are:

  1. Entertainment industry:AI can create voice-overs for movies, TV shows, and commercials. Also, YouTubers can use it to create faceless YouTube channels or just add a narrator to their videos.
  2. Call centers and customer service: Although it's not idea, we can use AI to provide automated responses to general customer inquiries.
  3. Video games: A much more affordable voice-over solution for for characters and in game narration.
  4. Education: AI voice overs can be used to provide audio content for online courses and textbooks.
  5. Repurposing online articles into audio.
  6. Podcasts and audiobooks: AI text-to-voice software can be used to create audio content for podcasts and audiobooks.
  7. Navigation systems: Although not many people are making their own navigation assistants, this is a classic case use for AI text. 

Overall, AI text-to-voice software has a wide range of commercial applications, and its use is growing rapidly in various industries.

Should I Consider Hiring a Human Voice Actor?

Human narrators absolutely have a place in 2023 and beyond. Yes, they will be splitting more and more marketshare each year to these new AI programs, but many people still prefer to pay the premium price of hiring a professional narrator. 

Although AI text to voice tools are powerful and can produce lifelike results, they still require time and effort, especially if you're creating long form narrations like you might have with something like an Audiobook.

You can read more about my own experience working with a human narrator from the website voices.com.

Viva la human narrator!

What Is an API for a Text to Voice Program?

You might have noticed I mentioned which programs had APIs. This means that the company lets other developers use their code in their projects. Essentially, if you wanted to make a software product that integrated text to voice to functionality in the same way as say, Play.HT, you could do that. It's not cheap and there are usually pretty long lists of what you can and can't do, but they are very exciting if you have a good idea for how to use them. 

Why Didn't You Include Descript?

You'll notice a few omissions from this list that might have been on similar ones across the internet. 

Descript wasn't include because it just isn't a good solution for straight text to audio. It's fantastic for changing your own voice and "overdubbing" but it is not a valid solution for straight text to voice. I'm somewhat surprised that so many people seem to promote it as if it is good for text to audio on its own. It is a great tool, and I recommend it for other things, but not for this. 

A couple other tools that I have seen mentioned but didn't add were Respeaker and Respeecher: These tools both required setting up demos to use. Sorry, but no. 

We also didn't include Google Text to Speech or Amazon Poly due to their non-userfriendly interfaces. These are much better fits for enterprise companies using text to voice AI at scale.
