Text to speech in android

1) Create a new Android project go to
file-> new Android application-> Type the Application name as:- TextToSpeech
package name as:-com.example.texttospeech
then click next

                      




2) Then follow these steps:-



                     

click next

3)
                              

                     

click next

4)

                     

5) click next and change the Activity name according to your need in this project.

I have used the default name as activity_main.


                     

and click finish

6) The layout file will open 

    click to activity_main.xml next to graphical layout tab
    and write this code.

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

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

   <EditText

     android:id="@+id/txtText"

     android:layout_width="fill_parent"

     android:layout_height="wrap_content"

     android:hint="@string/editText" />

  <Button

    android:id="@+id/btnSpeak"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:layout_gravity="center_horizontal"

   android:layout_marginTop="50dp"

   android:text="@string/btnSpeak" />

  </LinearLayout>




7) Go to values folder -> Strings.xml in that put these fields


<?xml version="1.0" encoding="utf-8"?> 

<resources>

<string name="app_name">TextToSpeech</string>

<string name="btnSpeak">Speak Out</string>

<string name="action_settings">Settings</string>

<string name="editText">enter your text</string>

</resources>


8) Go to source folder open MainActivity.java
    and write this code.

    

package com.example.texttospeech;

import java.util.Locale;

import android.speech.tts.TextToSpeech;

import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.EditText;

public class MainActivity extends Activity  implements TextToSpeech.OnInitListener {

private TextToSpeech tts;

private Button btnSpeak;

private EditText txtText;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_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

protected void onDestroy() {

// TODO Auto-generated method stub

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() {

// TODO Auto-generated method stub

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

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

}

}

9) Your done with this now compile your project and run it.

    Before click on run connect your android phone to your PC and in your mobile 

    Developer settings click on USB Debugging option.

Note: In some of the phones  Text to speech engines are not installed you have to installed it

through Google play store.

else you can use the following code to check it .

Intent intent = new Intent();
intent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(intent, 0);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 0){
    if(resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS){
    Toast.makeText(getApplicationContext(),"Already Installed", Toast.LENGTH_LONG).show();
} else {
    Intent installIntent = new Intent();
    installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
    startActivity(installIntent);
    Toast.makeText(getApplicationContext(),"Installed Now", Toast.LENGTH_LONG).show();
}
