title: TTS-UtteranceProgressListener not being called
body: <p>I don't want to put all my code here, so I'm just putting the relevant pieces.  If you need more, feel free to ask.  </p>
  
  <p>I'm using Text To Speech (TTS) which leads to a speech listener after it asks a question... I found through Log outputs that TTS's onInit is being called, but the UtteranceProgressListener is not and I can't figure out why.  Any help is appreciated.</p>
  
  <pre><code>// ---Initialize TTS variables---
  
          // Implement Text to speech feature
          tts = new TextToSpeech(this, new ttsInitListener());
  
          // set listener to the TTS engine
          tts.setOnUtteranceProgressListener(new ttsUtteranceListener());
  
          if (!tts.isSpeaking()) {
              tts.speak("Speak to me", TextToSpeech.QUEUE_FLUSH, null);
          }

  <pre><code>// --- TEXT TO SPEECH &amp;&amp; SPEECH TO TEXT METHODS ---
  
  class ttsInitListener implements OnInitListener {
  
      @Override
      public void onInit(int status) {
  
          if (status == TextToSpeech.SUCCESS) {
              tts.setLanguage(Locale.getDefault());
  
          } else {
              tts = null;
              Toast.makeText(mContext, "Failed to initialize TTS engine.",
                      Toast.LENGTH_SHORT).show();
          }
      }
  }
  
  class ttsUtteranceListener extends UtteranceProgressListener {
  
      @Override
      public void onDone(String utteranceId) {
          if (processStart) {
              speech.startListening(intent);
          } else {
              ...
          }
  
      }
  
      @Override
      public void onError(String utteranceId) {
      }
  
      @Override
      public void onStart(String utteranceId) {
      }    
  }

  <p>I added log outputs to all of the my TTS and Speech methods.  UtteranceProgressListener's onStart isn't even being called:</p>
