We have found some limitations when testing on HTC phones. In general it is not good idea to install COrvus on the cheapest phones from untrusted producers. It will probably work but probably not. It’s always better to send query or test before buying such a cheap phone.


Q: Which text to speech (TTS) synthesis can I use?

A: Any TTS supported for Android. We use Android TTS infrastructure, thus COrvus can speak using any TTS installed on the phone.
