2. Bouyomichan
"Bouyomichan" is a free text-to-speech app available for Windows.
It is an app that can read text with the so-called "Yukkuri Voice," and can be downloaded for free from the software creator's website.
Yukkuri Voice is not realistic, but the sound quality is sufficient for hearing and understanding the content.
It is perfect for uses where it is enough to just be able to hear the content.
The operation is very lightweight and does not put a strain on the PC, so it is widely used for reading game commentary comments.
Another point is that it has a small capacity of only 1.5MB, whereas many text-to-speech apps for Windows have a download size of 1GB or more.
Commercial use is also possible for free.
3. Textalk
Textalk is a text-to-speech app for Windows.
The speech synthesis engines used are:
- OpenJTalk
- Microsoft Haruka Desktop(SAPI5)
The spoken files can be saved in MP3 and WAV formats.
Since it is an app whose updates stopped in 2015 and the speech synthesis engine is older, it is not as realistic as the latest AI text-to-speech apps for Windows, but it possesses the minimum text-to-speech functions.
There are no particular restrictions on the use of the spoken audio, so commercial use is also possible.

SofTalk is a text-to-speech app for Windows.
It is free software and can be used for free.

How to read text aloud using standard Windows features
Finally, we will introduce the text-to-speech features standardly equipped in Windows.
Windows Narrator feature
Windows is equipped with "Narrator" as a feature for improving accessibility.
The setup method is very simple.
First, open the "Settings" app.
In the "Settings" app, select "Ease of Access."
In "Ease of Access," select "Narrator."
From "Turn on Narrator," turn the Narrator feature on.
Now you have successfully turned on the Windows Narrator feature.
When the Narrator feature is turned on, all text displayed on the Windows screen, including menus, can be read aloud.
For example, when you open a browser, the displayed text is read aloud in order from the top.
No save function
However, since the Windows Narrator feature is strictly for improving accessibility, it does not have a function to save the audio.
If you want to save the audio as an MP3 file or similar for use, we recommend using a text-to-speech app like Ondoku.
