Text-to-speech apps using AI are so realistic, it's like a real human is speaking!
1. Ondoku
"Ondoku" is a web-app style text-to-speech service that can be used for free.

Even though "Ondoku" is a free web app, it adopts the latest AI!
It is capable of high-quality reading with very realistic voices.
As a web app, another benefit is that you can use the latest AI for text-to-speech even on low-performance PCs.
The read-aloud audio can be downloaded as an MP3 file or a WAV file.
Long text-to-speech is possible even though it's free!
"Ondoku" allows free text-to-speech without registration or login!
The number of characters that can be read for free is:
- Before registration/login: 1,000 characters
- After registration/login: 5,000 characters
With this much, you can use it easily and immediately whenever you want read-aloud audio.
Commercial use is OK for free!
"Ondoku" allows commercial use even when using it for free.
Many other text-to-speech apps require a license purchase for commercial use, so "Ondoku" is recommended when you want to use read-aloud audio commercially.

Equipped with foreign language reading and conversation functions
"Ondoku" is also equipped with foreign language reading and conversation functions.

2. Bouyomi-chan
"Bouyomi-chan" is a free text-to-speech app available for Windows.
It is an app that can read text in the so-called "Yukkuri voice," and it can be downloaded for free from the software creator's website.
While Yukkuri voice is not realistic, the sound quality is sufficient for hearing and understanding the content.
It is perfect for purposes where it is sufficient to simply hear and understand the content at a minimum.
Because its operation is very lightweight and does not put a burden on the PC, it is widely used for reading comments in game streaming.
While many text-to-speech apps for Windows have download sizes of 1GB or more, it is only 1.5MB, making its small capacity a key point.
Commercial use is also possible for free.
3. TextTalk
TextTalk is a text-to-speech app for Windows.
It adopts the speech synthesis engines:
- OpenJTalk
- Microsoft Haruka Desktop(SAPI5)
Read-aloud files can be saved in MP3 and WAV formats.
Because development stopped in 2015 and the speech synthesis engine is somewhat old, it is not as realistic as the latest AI text-to-speech apps for Windows, but it possesses the minimum necessary text-to-speech functions.
Since no particular restrictions are placed on the use of the read-aloud audio, commercial use is also possible.
4. SofTalk
SofTalk is a text-to-speech app for Windows.
It is free software and can be used for free.
It adopts the speech synthesis engines:
- Original speech synthesis engine
- MikoVoice
- SAPI (Utauyomi & Utauyomi 2, Open JTalk, Microsoft Speech Platform)
Previously, it was used alongside Bouyomi-chan for Yukkuri voice reading, but currently, it does not support Yukkuri voice (AquesTalk).
The app itself is free, but caution is required as you must follow the terms of use of the speech synthesis engine if you want to use it commercially.
5. COEIROINK
COEIROINK is a text-to-speech app that can be used for free.
It is compatible with Windows and Mac.

The app download size is relatively large at around 1GB, and the download size when adding voice tones is also large, so be careful if you are using anything other than a fixed line.
The Windows app has a GPU version and a CPU version, and on high-performance PCs equipped with a GPU (graphics card), it can be used more comfortably.
It is a free app, but be careful with the terms of use
COEIROINK can be downloaded for free, but be careful with the terms of use.
When using audio generated with COEIROINK, credit is mandatory regardless of whether it is commercial or non-commercial.

Be careful with the terms of use in case of commercial use
The software itself can be used for free regardless of whether it is commercial or non-commercial.
However, credit notation that shows VOICEVOX was used is mandatory.
Also, in addition to the terms of use for VOICEVOX itself, you must follow the terms of use for each character, so caution is necessary, especially for commercial use.

For individual use, the license is set relatively leniently, apart from the credit notation being mandatory.
Registration for use is also unnecessary when using it in videos posted to video sites.
Even when using it for media distribution of music or videos, it's OK just to perform use registration from the website.
However, a separate estimate is required for use by corporations or for individual use in work contracted from a corporation.
How to Read Aloud Using Windows Standard Features
Finally, we will introduce the text-to-speech features standardly installed in Windows.
Windows Narrator Function
Windows is equipped with "Narrator" as a feature to improve accessibility.
The setup method is very easy.
First, open the "Settings" app.
In the "Settings" app, select "Ease of Access".
In "Ease of Access", select "Narrator".
Turn on the Narrator function from "Turn on Narrator".
With this, you have turned on the Windows Narrator function.
When the Narrator function is turned on, everything displayed on the Windows screen, including menus, can be read aloud.
For example, if you open a browser, the displayed text will be read aloud in order from the top.
There is no save function
However, since the Windows Narrator function is strictly for improving accessibility, it does not have a function to save the audio.
