If a language TTS hasn't been downloaded... #259

Open yasaman93 opened 3 years ago

yasaman93 commented 3 years ago

Hello and thank you for this library.

I want to know if a language hasn't been downloaded on a device, how can I use this library to download it and prevent this error?: speak failed: not bound to TTS engine

I did some tests, and I realized that when the application is closed and I open the app, It seems that this library automatically download the desired language tts. But when the app is open and I manually clear tts engine app data, I get this error: speak failed: not bound to TTS engine

Is the way I'm testing this issue wrong? Or there is some way to download the language programmatically?

not bound to TTS engine should be related to the engine itself such as the Google TTS engine (com.google.android.tts) and not the language.

Hello, thanks for the library, just bumping this old thread, is there anyway to programatically download a language pack? it does not appear to be automatic for me nor can i find any reference documents to support that it does. thanks.

@quickratio this isn't an option at this time. If there is a known way to do so in Android, I don't mind implementing an option to do so through this package.

@dlutton understood, thanks for your response and efforts! :)
