Android TextToSpeech.synthesizeToFile() file is not created

Question

I am trying to implement a pause and play function to some text using tts and MediaPlayer. However, I can\'t seem to be able to create a .wav file using the synthesizeToFile

Answer 1

The method synthesizeToFile is asynchronous thus you should do the checking

File fileTTS = new File(destFileName);

if (fileTTS.exists()) {
    Log.d(TAG, "successfully created fileTTS");
}
else {
    Log.d(TAG, "failed while creating fileTTS");
}

in onUtteranceCompletedListener or UtteranceProgressListener
