At Ondoku, we continue to make daily improvements so that everyone can use content in their favorite language and voice.

With this update, we now support 80 languages and dialects.

Previously, we supported about 300 speakers.

With this update, we now support 650 speakers.

Sample pages are available for some voices. Please make use of them.

Speaker: Multilingual

In addition, a new multilingual speaker has been introduced.
