Best Text-To-Speech Online (TTS) With Natural Voices [Audio Samples]
Today I’m going to share with you one of the best text-to-speech online apps.
I’ve been looking for some time for a good text-to-speech service that I can use to turn simple text into audio and finally found a software that sounds more natural and closer to a human voice.
What is a text-to-speech service?

A text-to-speech service (TTS) is a service, software, or an app that enables you to convert any text into an audio file.
This kind of software can be useful in many cases, especially when English is not your primary language (as is my case).
For example, you can use a text-to-speech app to create voice-overs for your videos without having to pay thousands of dollars on voice-over services.
Another use for a TTS service could be to create audio versions of your blog posts.
Some people prefer to listen to audio instead of reading a long article. They can also listen to the audio while they drive to work, or while doing housework.
You can also use a text-to-speech app to add more value to your digital course or product. For example, you can make an audio version of your ebook and sell it as an upsell.
You can even sell voice-overs created with a TTS service at a lower price on websites like Fiverr and earn money.
What is the best text-to-speech app?
Most of the text-to-speech apps I found online are either very expensive or sound very unnatural and robotic.
There are also some free text-to-speech services, but these are usually not very good.
Most of them have a very low character limit per the text you can convert, do not allow you to make voice-overs that can be used commercially, or just sound really bad.
Recently, I came across an online text-to-speech service which I think is very good. In fact, is way better than the other online text-to-speech services I ever found.
This app is called ScriptVocalizer and has been developed by Andrew Darius and the same team behind Explaindio video creator (I was already a customer of this software before the ScriptVocalizer launch).
Script Vocalizer uses the Amazon Polly engine, which is currently one of the most advanced text-to-speech technologies.
I’ve purchased a one-year license of this software after its launch and I’m pleasantly impressed by the quality of the voice-over.
ScriptVocalizer is a cloud-based tool, which means you don’t have to install
The app is extremely easy to use.
Here’s how it looks like.

After you purchase
The standard license allows you to convert up to 1000 characters of text into speech at once, which is more than enough for my needs.
If I’m not mistaken, there is also an upsell that gives you a higher limit. That would be a better option if you are a book author and you need to convert entire books to audio.
ScriptVocalizer has a total of 47 different male and female voices, each named with a different human name so it is easy to remember which voice you liked.
This app comes with five English variations and accents:
- English (US)
- English (British)
- English (Australian)
- English (Welsh)
- English (Indian)
And other 20+ languages, variations and accents.
- Chinese, Mandarin
- Danish
- Dutch
- French
- French (Canadian)
- German
- Hindi
- Icelandic
- Italian
- Japanese
- Korean
- Norwegian
- Polish
- Portuguese (Brazilian)
- Portuguese (European)
- Romanian
- Russian
- Spanish
- Spanish (Latin American)
- Spanish, Mexican
- Swedish
- Turkish
- Welsh
Many of the languages have also gender options, or have multiple voice variations.
The US English has 8 variations available.

I’m sure you are anxious to hear how the voice-overs created with this software sound, so I’ve attached a few audio samples.
English (US) – Matthew
English (US) – Joanna
English (US) – Sally
English (US) – Kendra
English (US) – Justin
English (US) – Joey
English (US) – Ivy
English (Australian) – Russel
English (Australian) – Nicole
English (British) – Brian
English (British) – Amy
English (British) – Emma
English (Welsh) – Geraint
There are many other languages and voice variations and accents, but these samples should be enough to help you make an idea on how the voices generated with this text-to-speech online service sound.
Of course, the more natural the provided text sound in a specific dialect, the better the audio will sound. All the samples above were generated using the same text in US English.
ScriptVocalizer is not a free service, but I consider it to be very affordable.
Currently, there are two license types:
- Monthly, which costs $9.95/month
- Annual, which costs $69.65/year
These prices might go up in the future since the app was just recently launched. Also, there’s a note under the buy buttons saying that these prices are reduced with 80% off the normal price.
Both of these licenses give you the same features and allows you to create unlimited audio files, each with up to 1,000 words.
The annual license is just the monthly license at a discounted price (that’s only about $5.80/month).

Conclusion
A text-to-speech can be very useful when you are a blogger, a book author, if you want to start a YouTube channel and English is not your native language, or if you just don’t want to record your voice.
I cannot say that ScriptVocalizer is 100% perfect, but it’s certainly the best text-to-speech online app I found.
Hey!
We have a similar text to speech application with 57 natural-sounding it called Notevibes.
Also, we launch an affiliate program you can make extra money with your blog.
I listened to all the English voices, all flavors, including Matthew which is the best. None of them sound better (I mean the prosody) than David and Zira, US voices that come free with Windows 7 and up. So, for US English the expense is not justified.
For the other languages though, it might be. Although, Microsoft provides TTS voices customized to the Windows versions in other languages (Andrei for Romanian, as an example). I don’t know if they’re as good as David and Zira, but they may, since Microsoft is kind of the top software company in the world.
