    // Get display items for later interaction
    Button speakButton = (Button) findViewById(R.id.speakButton);

    mList = (ListView) findViewById(R.id.list);

    // Check to see if a recognition activity is present
    PackageManager pm = getPackageManager();
    List<ResolveInfo> activities = pm.queryIntentActivities(
            new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
    if (activities.size() != 0) {
        speakButton.setOnClickListener(this);
    } else {

    if (v.getId() == R.id.speakButton) {
        startVoiceRecognitionActivity();
    }
}

/**

 */
private void startVoiceRecognitionActivity() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
    startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}

/**
 * Handle the results from the recognition activity.
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
        // Fill the list view with the strings the recognizer thought it could have heard
        ArrayList<String> matches = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);
        mList.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,

For using RecognizerIntent device must have Google voice search because RecognizerIntent means an intent launched for using google voice listening engine.

Also,have you checked your internet connection ,it will not work if there is no wifi or net connection. Don't forget permission 

        <uses-permission android:name="android.permission.INTERNET" />

That is the output you should be getting based on your code. You have asked it to disable the button and re-name it if there is no speech recognition available. Speech recognition does not come standard with the Android SDK, you have to download and install an app to handle it. See this thread: http://groups.google.com/group/android-developers/browse_thread/thread/f11f7598ff60f4ae?pli=1
