Notice: New Languages and More Speakers Added to Multilingual AI Voice
Aug. 28, 2026
The AI voice synthesis service "Ondoku" has started providing a "Multilingual" voice feature that can naturally read out multiple languages with a single voice.
I want to read out text that mixes English and Japanese, but switching voices is a hassle...
I want to create teaching materials that mix Chinese and English...
We have the solution for you!
Read multiple languages smoothly with Multilingual voices!
"Multilingual" has been newly added to Ondoku's language selection.
You can find Multilingual at the very top of the language list.
By selecting "Multilingual," over 40 multilingual voices become available!
The parentheses () following the speaker's name indicate which language is the base language for that speaker.
For example, in the case of "Isabella(it)," it indicates that Italian is the base language.
The contents of the parentheses () correspond to language codes.
*The "Multilingual" speakers that were previously displayed when selecting individual languages (such as English or Japanese) have now been consolidated here.
Please note that multilingual speakers will no longer be displayed under individual languages.
Features of Multilingual
They can speak various languages, including English, Chinese, Spanish, Arabic, and more.
Speaker: Isabella(it) Pitch: 0
With multilingual speakers, even if you enter text in multiple languages, they will read it out with native pronunciation for each language.
