        android:layout_marginTop="30dp"

        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

Step 3: Android Java Code 

package com.example.activity;

import java.util.ArrayList;

import com.example.speechtotext.R;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.speech.RecognizerIntent;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;

public class SpeechActivity extends Activity {

TextView displayText;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.speech_layout);

displayText = (TextView) findViewById(R.id.displayTextView);

Button speakButton = (Button) findViewById(R.id.speakButton);

speakButton.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Intent in = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

in.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");

try {

startActivityForResult(in, 1);

} catch (Exception e) {

// TODO: handle exception

Toast.makeText(

getApplicationContext(),

"sorry, your device doesn't support speech to text feature",

Toast.LENGTH_LONG).show();

}

}

});

}

@Override

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

// TODO Auto-generated method stub

if (requestCode == 1) {

if (resultCode == RESULT_OK && data != null) {

ArrayList<String> text = data

.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

displayText.setText(text.get(0));

}

}

super.onActivityResult(requestCode, resultCode, data);

}

}

The Final Result looks like this
