User the RecognizerIntent to use speech input in your application. You can have a look at the sample code VoiceRecognition from Google.

Hi Thanks for the reply it was great help however can you do me one more favor, i tried to run the code and created an xml with appropriate id's i even set the permissions for AUDIO_RECORD but when i run the app the button has text RECOGNIZER NOT PRESENT on it, which means im surely missing some hardware permission or something because text to speech was working fine earlier.. any idea what it might be??? – Umer Hassam Mar 09 '11 at 23:06
@umer: The Intent makes use of any speech recognition service available on the device. Make sure "Voice Search" (from Android market : https://market.android.com/details?id=com.google.android.voicesearch) is installed on your device. – Chris Mar 09 '11 at 23:44

@PratikButani looks like google have removed/deprecated the demo. Googling around lead to this example https://www.developer.com/ws/android/programming/exploring-the-android-speech-api-for-voice-recognition.html – angryITguy Jan 22 '19 at 00:24

This is the code

    public class MainActivity extends Activity {

    protected static final int RESULT_SPEECH = 1;

    private ImageButton btnSpeak;
    private TextView txtText;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        txtText = (TextView) findViewById(R.id.txtText);

        btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

        btnSpeak.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent intent = new Intent(
                        RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

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

                try {
                    startActivityForResult(intent, RESULT_SPEECH);
                    txtText.setText("");
                } catch (ActivityNotFoundException a) {
                    Toast t = Toast.makeText(getApplicationContext(),
                            "Opps! Your device doesn't support Speech to Text",
                            Toast.LENGTH_SHORT);
                    t.show();
                }
            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
        case RESULT_SPEECH: {
            if (resultCode == RESULT_OK && null != data) {

                ArrayList<String> text = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                txtText.setText(text.get(0));
            }
            break;
        }

        }
    }
}
