Text To Speech Pico

It's the speech synthesis which is named Pico and was distributed on old androids and new androids that don't use Google's speech synthesis. It's under Apache Licence 2
This speech synthesis motor can use SSML ( contrary to Google's)

You will have to install languages separately ( but sometimes they are already installed weirdly).

You can write to me, if the app crashes or it bugs ( I could try to correct it , but don't count on it) . But don't bother to ask to correct the languages. I'm unable to. And this motor is not updated anymore. :(
