Code for text to speech conversion in Android.
Steps:
- Start Eclipse IDE.
- Create a new project.
- Create a MainActivity.java file.
- Create an activity_main.xml for layout design.
MainActivity.java
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 e1;
Button b1;
TextToSpeech tts;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
e1=(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 = e1.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 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)
{
if(status==TextToSpeech.SUCCESS)
{
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),"engine installed", 1000).show();
}
if(status==TextToSpeech.ERROR)
{
Toast.makeText(getApplicationContext(),"engine not installed", 1000).show();
}
}
}
Code - activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView1"
android:layout_below="@+id/textView1"
android:layout_marginLeft="35dp"
android:layout_marginTop="32dp"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
