Android TextToSpeech Example

TextToSpeech class is responsible to convert text into speech. It provides a lot of methods to control the speech such as setSpeedRate(), setPitch() etc.

In this example, we are going to see the android texttospeech example with speed and pitch option.

activity_main.xml

Drag 2 textviews, 1 edittext, 1 spinner and 1 button for the layout. Now the activity_main.xml file will look like this:

File: activity_main.xml

<RelativeLayout xmlns:androclass="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textView1"
        android:layout_alignBottom="@+id/textView1"
        android:layout_alignParentRight="true"
        android:layout_marginRight="58dp"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/editText1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="28dp"
        android:text="Speak" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/button1"
        android:layout_marginTop="62dp"
        android:layout_toLeftOf="@+id/editText1"
        android:text="Speed:" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView2"
        android:layout_alignParentTop="true"
        android:layout_marginTop="42dp"
        android:text="Text:" />

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/button1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="43dp" />

</RelativeLayout>

Activity class

Let's see the code to speak the given text.

File: MainActivity.java

        speakOut();
    }

});
}


@Override

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!");}

}

@Override
public void onDestroy() {

    tts.stop();
    tts.shutdown();

super.onDestroy();
}

private void setSpeed(){

		tts.setSpeechRate(2.0f);
	}
	//for setting pitch you may call 
	//tts.setPitch(1.0f);//default 1.0
}

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

private void loadSpinnerData() {
	//Data for speed Spinner
    List<String> lables = new ArrayList<String>();
    lables.add("Very Slow");
    lables.add("Slow");
    lables.add("Normal");
    lables.add("Fast");
    lables.add("Very Fast");
    
    // Creating adapter for spinner
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, lables);

    // Drop down layout style - list view with radio button
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // attaching data adapter to spinner
    speedSpinner.setAdapter(dataAdapter);
    
  }

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position,
        long id) {
    // On selecting a spinner item
    speed = parent.getItemAtPosition(position).toString();

    Toast.makeText(parent.getContext(), "You selected: " + speed,
            Toast.LENGTH_LONG).show();
}

@Override
public void onNothingSelected(AdapterView<?> arg0) {
   
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
}

}

You need to run it on the Real Device (e.g. Mobile) to test the application.
