You can use the method synthetizeToFile(). You have to create a File with FileProvider to avoid restricted files above api 24. You have also to pass a request id.

String utteranceId = "MyUtteranceId"
File file = /* file obtained with FileProvider */
int result = tts.synthesizeToFile(text, null, file, utteranceId);
if (result == TextToSpeech.SUCCESS) {
    // It was successfull.
} else {
    // Error occurred
}

This method returns an int representing the result (error or success). I recommend you to move the synthetize on a background thread and dispatch the result on the UI thread after.
