Text to speech not working on android device

Question

Below is my code.I am unable to hear the voice in my kitkat device.Toast is appearing but voice is not playing.I am following this tutorial

https://www.tutorialspoint.com/android/android_text_to_speech.htm

package com.example.insert;
import android.os.Parcelable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import java.util.Locale;
import android.widget.Toast;
import android.util.Log;
import java.lang.Object;


public class SecondActivity extends AppCompatActivity {
    TextToSpeech t1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        String emailid;
        emailid = "Hi,say your email id";

        t1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    int result = t1.setLanguage(Locale.US);
                    if (result == TextToSpeech.LANG_MISSING_DATA
                            || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        Toast.makeText(getApplicationContext(), "This language is not supported", Toast.LENGTH_SHORT).show();
                    }
                } else {
                    Toast.makeText(getApplicationContext(), "Initialization failed", Toast.LENGTH_SHORT).show();
                }

            }
        });


       // Toast.makeText(getApplicationContext(), emailid, Toast.LENGTH_SHORT).show();
        t1.speak(emailid, TextToSpeech.QUEUE_FLUSH, null);

    }


    @Override
    protected void onDestroy() {
        super.onDestroy();
        // Don't forget to shutdown tts!
        if (t1 != null) {
            Log.e("TTS","speech on destroy");
            t1.stop();
            t1.shutdown();
        }
    }
}

I have followed this post on stackoverflow.

Android TTS doesn't speak

But i didn't understand gameover,line and definition_string.

guys help me

you should call t1.speak(...) after onInit(...) received. – Joe Mizuno Mar 17 '17 at 06:17 — Joe Mizuno, Mar 17 '17 at 06:17

Here is my code. this code works on Nexus9.(Locale is Japan)

public class MainActivity extends AppCompatActivity{

    static final String TAG = "TTS";
    TextToSpeech mTts;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final String emailid;
        emailid = "こんにちは";

        mTts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    int result = mTts.setLanguage(Locale.JAPAN);
                    if (result == TextToSpeech.LANG_MISSING_DATA
                            || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        Toast.makeText(getApplicationContext(), "This language is not supported", Toast.LENGTH_SHORT).show();
                    }
                    else{
                        Log.v("TTS","onInit succeeded");
                        speak(emailid);
                    }
                } else {
                    Toast.makeText(getApplicationContext(), "Initialization failed", Toast.LENGTH_SHORT).show();
                }

            }
        });
        setVolumeControlStream(AudioManager.STREAM_MUSIC);
    }

    void speak(String s){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Log.v(TAG, "Speak new API");
            Bundle bundle = new Bundle();
            bundle.putInt(TextToSpeech.Engine.KEY_PARAM_STREAM, AudioManager.STREAM_MUSIC);
            mTts.speak(s, TextToSpeech.QUEUE_FLUSH, bundle, null);
        } else {
            Log.v(TAG, "Speak old API");
            HashMap<String, String> param = new HashMap<>();
            param.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_MUSIC));
            mTts.speak(s, TextToSpeech.QUEUE_FLUSH, param);
        }
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        // Don't forget to shutdown tts!
        if (mTts != null) {
            Log.v(TAG,"onDestroy: shutdown TTS");
            mTts.stop();
            mTts.shutdown();
        }
    }
}

It takes some time to initialise. Put the speak code in onClick method. If you trigger that method on button click, it will speak.

someButton.setOnClickListener(new OnClickListener{
onClick(View view){
t1.speak(emailid, TextToSpeech.QUEUE_FLUSH, null);
   }
}

I guess problem is with Locale. Please print logs. try out following code.

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import java.util.Locale;
import android.widget.Toast;


public class SecondActivity extends AppCompatActivity  {
    TextToSpeech t1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        String emailid;
        emailid="Hi,say your email id";

         t1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if(status == TextToSpeech.SUCCESS) {
                    t1.setLanguage(Locale.US);
                    if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                         Log.d(TAG, "This Language is not supported");
                }
                }else{
                    Log.d(TAG, "Initilization Failed!");
               }

            }
        });


        Toast.makeText(getApplicationContext(), emailid,Toast.LENGTH_SHORT).show();
        t1.speak(emailid, TextToSpeech.QUEUE_FLUSH, null);

    }


@Override
 protected void onDestroy() {
    super.onDestroy();
    // Don't forget to shutdown tts!
    if (mTextToSpeech != null) {
        Log.d(TAG, "speach on destroy");
        t1.stop();
        t1.shutdown();
    }
}

I have tried toast to see the output.I have edited the question.I have added the new code.Please check.No toast is appearing — Lakshmi, Mar 10 '17 at 13:46
If no toast is appearing, I guess problem is with your String. Please change your string try to give some simple message is debug. In your String "Hi,say your email id" I guess ttf is not able to identify. Please try with "Hi, say your email id" or some simple string. — Rohit, Mar 13 '17 at 04:51

I don't understand why didn't you implement your main Activity class from TextToSpeech.OnInitListener...!

Here's your answer:

import java.util.Locale;

import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class AndroidTextToSpeechActivity extends Activity implements
        TextToSpeech.OnInitListener {
    /** Called when the activity is first created. */

    private TextToSpeech tts;
    private Button btnSpeak;
    private EditText txtText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        tts = new TextToSpeech(this, this);

        btnSpeak = (Button) findViewById(R.id.btnSpeak);

        txtText = (EditText) findViewById(R.id.txtText);

        // button on click event
        btnSpeak.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                speakOut();
            }

        });
    }

    @Override
    public void onDestroy() {
        // Don't forget to shutdown tts!
        if (tts != null) {
            tts.stop();
            tts.shutdown();
        }
        super.onDestroy();
    }

    @Override
    public void onInit(int status) {

        if (status == TextToSpeech.SUCCESS) {

            int result = tts.setLanguage(Locale.US);

            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e("TTS", "This Language is not supported");
            } else {
                btnSpeak.setEnabled(true);
                speakOut();
            }

        } else {
            Log.e("TTS", "Initilization Failed!");
        }

    }

    private void speakOut() {

        String text = txtText.getText().toString();

        tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
    }
}
