Text to Speech not working as expected

android, text-to-speech

Solution

You can do something like this:

@Override
public void onInit(int status) {

    if (status == TextToSpeech.SUCCESS) {
        reader.setLanguage(canada);
        reader.setPitch(0.9f);
        Log.e("Init", "Success");
        readerInit = true;

        // wait a little for the initialization to complete
        Handler h = new Handler();
        h.postDelayed(new Runnable() {
            @Override
            public void run() {
                // run your code here
                speak();
            }
        }, 400);

    }

    else {
        System.out.println("Something went wrong.");
    }

}

It's not very nice, but it works. I hope somebody will find a better solution...

Problem

I have followed several tutorials, but I am experiencing the same problem. First, here is my simple code: ``` import java.util.Locale; import android.app.Activity; import android.content.Intent; import android.content.pm.ActivityInfo; import android.os.Bundle; import android.speech.tts.TextToSpeech; import android.speech.tts.TextToSpeech.OnInitListener; import android.util.Log; public class AchievementsActivity extends Activity implements OnInitListener { TextToSpeech reader; Locale canada; boolean readerInit = false; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); canada = Locale.ENGLISH; reader = new TextToSpeech(this, this); //speak(); // while (reader.isSpeaking()) {} //waiting for reader to finish speaking } @Override public void onStart() { super.onStart(); //speak(); } @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { reader.setLanguage(canada); reader.setPitch(0.9f); Log.e("Init", "Success"); readerInit = true; speak(); } else System.out.println("Something went wrong."); } public void speak() { reader.speak("You currently have no achievements.", TextToSpeech.QUEUE_FLUSH, null); } } ``` Now, notice the first speak in `onCreate()` which I have commented out, and the second in `onStart()` which I have also commented out. The reason for this is obvious based on what I receive in LogCat. For some reason, they are called before the initialization of the `reader` is complete. So the only way I have this working right is by placing the `speak()` function immediately after the initialization is sure to complete inside its own method. So I was wondering if there is any way to wait for the initialization to complete, and then run `speak()` in `onCreate` or `onStart()`.
