Hello, I was wondering if it would be possible to use Android built-in text to speech with MOE and run this in iOS? something like this https://github.com/gotev/android-speech or this is a platform dependent ?
I checked the link that you provided, and it seems to use the android.speech API. This API is not implemented on MOE currently. Note, that while the API itself is open-source, the underlying speech engines might be closed source (I did not check what is included in AOSP).
You have the following options:
create a Java binding for an iOS TTS engine using Natjgen, and use that
port an existing Java (including ones with native parts + JNI binding) TTS engine
port the android.speech API and one of its speech engines that is released as open-source
