Create a simple app which reads out what you write

In this post you will be guided to create a simple android application which reads out loud the text you write. This application uses Text To Speech (TTS) class. This is a basic application which has 1 EditText field and a single button. The EditText field is basically takes input and once you tap that button, it will read the entered text. This program uses your default TTS output voice.

Demo:

When tapped on Speak, It reads loudly "Hello I'm Sid".

Implementing TTS Class:

public class MainActivity extends Activity implements TextToSpeech.OnInitListener

Overriding TTS onInit method:

@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 {  
        buttonSpeak.setEnabled(true);  
        speakOut();  
    }  
  
} else {  
    Log.e("TTS", "Initilization Failed!");  
}

Overriding TTS onDestroy method:

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

The speakOut method method:

private void speakOut() {  
String text = editText.getText().toString();  
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);  
}
