Jelly Bean Beep In Speech Recognition

Question

I've been looking through different threads and haven't found anything that has worked for me on the problem that I am experiencing. I'd like to get rid of the "beep" sound that you get when speech recognition starts. I'm working with Jelly Bean 4.2.2 so I'm not sure if the same problem is on early versions, if it is I'd also like a fix for that. Also, I was wondering if anyone has suggestions on how to respond to certain Speech Recognition Results. Please let me know how my code can be improvised to include those features.

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    boolean available = SpeechRecognizer.isRecognitionAvailable(this);
    Log.d("Speech", "available = " + available);
    mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
    mSpeechRecognizer.setRecognitionListener(new SpeechListener());
    mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
