package com.example.texttospeech;

 

import android.os.Bundle;

import android.app.Activity;

import android.content.Intent;

import android.speech.tts.TextToSpeech;

import android.speech.tts.TextToSpeech.OnInitListener;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

import android.widget.Toast;

 

      public class MainActivity extends Activity implements OnInitListener {

      EditText ee;

      Button b1;

      TextToSpeech tts;     

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

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

            b1=(Button)findViewById(R.id.button1);

            b1.setOnClickListener(new OnClickListener() {

                 

                  @Override

                  public void onClick(View v) {

                        // TODO Auto-generated method stub

                        String str=ee.getText().toString();

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

                  }

            });

           

            Intent i =new Intent();

            i.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);

            startActivityForResult(i, 1);                       

      } 

      @Override

      protected void onActivityResult(int requestCode, int resultCode, Intent data) {

      // TODO Auto-generated method stub

      super.onActivityResult(requestCode, resultCode, data);

     

      if(requestCode==1)

      {

            if(resultCode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)

            {

                  tts= new TextToSpeech(this,this);                 

            }                       

            else

            {

                  Intent i=new Intent();

                  i.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);

                  startActivity(i);                 

            }

      }     

   }

 

@Override

public void onInit(int status) {

      // TODO Auto-generated method stub

      if(status==TextToSpeech.SUCCESS)

      {

            Toast.makeText(getApplicationContext(), "engine installed",1000).show();

      }

     

      if(status==TextToSpeech.ERROR)

      {

            Toast.makeText(getApplicationContext(), "engine not installed", 1000).show();                      

      }

   }

}

activity_main.xml
 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
