Customer reviews


I used to use other Text-to-Speech software, but I was tired of the robotic voice. However, Ondoku is different! The first time I used Ondoku, I was surprised and fascinated by the smooth voice. Since then, I have been using Ondoku.


Engineer. Tokyo, Japan
I'm a blogger. I was looking for a Text-to-Speech tool when I received a request from the reader, saying, "It's hard to read text, so can you read it aloud on YouTube?" At that time, I met Ondoku. It can be easily embedded in blogs, and commercial use is also allowed, which is truly useful.


Blogger. CA, USA
We are using Ondoku for pre-learning videos for online training. We have a natural narration.


I'm using other Text-to-Speech softwares too, but the voice and pitch of Ondoku was very easy for me to listen to. This time I really wanted to use it in my presentation. It was so helpful.
