I am using Google TTS Engine for Text-to-speech for Hindi Language.
In onCreate Methode i have created an Intent to check whether voice data
installed, and it gives result to onActivityResult methode
@Overrideprotected void onActivityResult(int requestCode, int resultCode,
Intent data) {
switch (requestCode) {
case ACTIVITY_TTS_PASS:
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
tts = new TextToSpeech(getApplicationContext(), this);
int availability = tts.isLanguageAvailable(new Locale("hin-IND"));
switch(availability) {
case TextToSpeech.LANG_AVAILABLE:
Log.d("TTS", "Language available");
break;
case TextToSpeech.LANG_NOT_SUPPORTED:
Log.d("TTS", "Language not supported");
Intent installTTSIntent = new Intent();
installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
ArrayList<String> languages = new ArrayList<String>();
languages.add("hin-IND"); // hin - hindi, IND - INDIA
installTTSIntent.putStringArrayListExtra(
TextToSpeech.Engine.EXTRA_CHECK_VOICE_DATA_FOR,
languages);
startActivity(installTTSIntent);
break;
case TextToSpeech.LANG_MISSING_DATA:
Log.d("TTS", "Language missing data");
break;
case TextToSpeech.LANG_COUNTRY_AVAILABLE:
Log.d("TTS", "Contry available");
break;
default:
Log.d("TTS", "default");
}
}
else {
Log.d("TTS", "fail");
Intent installTTSIntent = new Intent();
installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
ArrayList<String> languages = new ArrayList<String>();
languages.add("hin-IND"); // hin - hindi, IND - INDIA
installTTSIntent.putStringArrayListExtra(
TextToSpeech.Engine.EXTRA_CHECK_VOICE_DATA_FOR, languages);
startActivity(installTTSIntent);
}
break;
default:
Log.d("TTS", "case default");
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
Initially it comes to case TextToSpeech.LANG_NOT_SUPPORTED and prompt to
install TTS data by selecting an option among list of languages. I selected
'Hindi(India)' and installed successfully.
Again checking tts.isLanguageAvailable(new Locale("hin-IND")) gives the same
result (i.e. TextToSpeech.LANG_NOT_SUPPORTED).
I am using android 4.4.4
Questions:
1. How can i check whether Google TTS Engine data is installed for Hindi
Language (check for locale "hin-IND" OR "hi-IN") ?
2. How Is there any other approach for the same ?
