Android TTS onUtteranceCompleted callback isn't getting called

Question

I am trying to get the Android TTS API to read my "utterance" and then call the onUtteranceCompleted() listener unsuccessfully. I've registered my TTS object and it returns SUCCESS, so I can't figure out for the life of me why my callback isn't getting called.

I've tried searching for help, but it seems others have difficulty with this too. Am I missing something simple?

Thanks for any help you can offer.

package com.test.mytts;

import java.util.HashMap;

import android.app.Activity;
import android.media.AudioManager;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.speech.tts.TextToSpeech.OnUtteranceCompletedListener;
import android.widget.TextView;
import android.widget.Toast;

public class MyTTS extends Activity implements OnInitListener, OnUtteranceCompletedListener
{   
    TextView tv;
    private TextToSpeech _tts;

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        tv = new TextView(this);

        tv.setText("MyTTS: ");

        super.onCreate(savedInstanceState);
        setContentView(tv);

        _tts = new TextToSpeech(this, this);
    }

    @Override
    public void onInit(int status) 
    {
        HashMap<String, String> myHashAlarm = new HashMap<String, String>();

        myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_NOTIFICATION));
        myHashAlarm.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "test");

        if (status == TextToSpeech.SUCCESS)
        {
            Toast.makeText(this, "Trying to speak...", Toast.LENGTH_SHORT).show();

            int result = _tts.setOnUtteranceCompletedListener(this);

            tv.append(String.valueOf(result));

            _tts.setSpeechRate((float) .5);

            _tts.speak("Testing one, two, three", TextToSpeech.QUEUE_ADD, myHashAlarm);
        }
        else
            Toast.makeText(this, "Failed to initialize TTS.", Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onUtteranceCompleted(String utteranceId) 
    {
        Toast.makeText(this, "onUtteranceCompleted", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onDestroy()
    {
        super.onDestroy();
        _tts.shutdown();
    }
}

I don't see anything wrong with what you have, but you are probably better off using Log statements than toasts for tracking whats going on. Then you can review the ordering in logcat. — Cheryl Simon, Jan 11 '11 at 00:28

Call the setOnUtteranceCompletedListener inside the onInit function of the tts object.

If you want to make any changes to the UI on the call of the onUtteranceCompleted function, add the code inside a runOnUIThread method.

And do remember to add the Hashmap param value while calling the speak() function

Example :

TextToSpeech tts= new TextToSpeech(context, new OnInitListener() {

 @Override
 public void onInit(int status) {

    mTts.setOnUtteranceCompletedListener(new OnUtteranceCompletedListener() {

        @Override
        public void onUtteranceCompleted(String utteranceId) {

            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                //UI changes
                }
            });
        }
    });

 }
});


HashMap<String, String> params = new HashMap<String, String>();

params.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID,"stringId");

tts.speak("Text to Speak",TextToSpeech.QUEUE_FLUSH, params);

I believe that unless you specify an utterance with an id, like:

map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, utteranceid);

your utterance completed method will not be called.

in this case, map is the Hashmap you pass to the engine when you speak.

Having same problem as mentioned above. And I do have this key added to the map and pass it on speak. weird... – Patrick Boos Jun 15 '11 at 01:45
i usually specify the listener each and every time I call speak. Might help. – ekawas Jun 16 '11 at 19:54
somehow i got it working now. but no idea why it is working now. something was kind of weird i guess. – Patrick Boos Jun 20 '11 at 01:29
The same problem, I had that unique key but not working? Maybe do i need any permission. Android 6.0.1 – nAkhmedov Apr 15 '17 at 16:16
