Android provide text to speech class. using this class we can easily create an message reader type application, using the method of this class we can control speed of narrating and sound pitch also.

Java source Code for Narrator:

import java.util.Locale;

import android.os.Bundle;

import android.app.Activity;

import android.speech.tts.TextToSpeech;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemSelectedListener;

import android.widget.ArrayAdapter;

import android.widget.Button;

import android.widget.EditText;

import android.widget.RadioButton;

import android.widget.RadioGroup;

import android.widget.RadioGroup.OnCheckedChangeListener;

import android.widget.Spinner;

public class MainActivity extends Activity implements

TextToSpeech.OnInitListener{

   String speed[] = {  "Very Slow", "Slow", "Normal", "Fast", "Very Fast"};

   Float speedf[] = {(float) 0.1,(float) 0.5,(float) 1.0,(float) 1.5,(float) 2.0};

   Spinner spspeed;

   Button btn;

   EditText emsg;

   RadioGroup rg;

   TextToSpeech tts;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

ArrayAdapter adp = new ArrayAdapter(MainActivity.this, android.R.layout.simple_spinner_item,speed);

 

spspeed = (Spinner)findViewById(R.id.spinner1);

btn = (Button)findViewById(R.id.button1);

emsg = (EditText)findViewById(R.id.editText1);

rg = (RadioGroup)findViewById(R.id.radioGroup1);

tts = new TextToSpeech(this,this);

spspeed.setAdapter(adp);

spspeed.setOnItemSelectedListener(new OnItemSelectedListener() {

@Override

public void onItemSelected(AdapterView arg0, View arg1,

int arg2, long arg3) {

// TODO Auto-generated method stub

tts.setSpeechRate(speedf[arg2]);

}

@Override

public void onNothingSelected(AdapterView arg0) {

// TODO Auto-generated method stub

tts.setSpeechRate((float)1.0);

}

});

rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {

public void onCheckedChanged(RadioGroup group, int checkedId) {

// TODO Auto-generated method stub

RadioButton rb = (RadioButton)findViewById(checkedId);

if(rb.isChecked())

{

String gen = rb.getText().toString();

if(gen.equals("Male"))

tts.setPitch(1.0f);

else

tts.setPitch(2.5f);

}

}

});

btn.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

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

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

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

@Override

public void onInit(int status) {

// TODO Auto-generated method stub

if (status == TextToSpeech.SUCCESS) {

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

   if (result == TextToSpeech.LANG_MISSING_DATA

           || result == TextToSpeech.LANG_NOT_SUPPORTED) {

       Log.e("TTS", "This Language is not supported");

   } else {

    btn.setEnabled(true);

   

   }

} else {

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

}

}

@Override

public void onDestroy() {

// Don't forget to shutdown tts!

if (tts != null) {

   tts.stop();

   tts.shutdown();

}

super.onDestroy();

}

}
