Is it possible to use android's speech recognition without showing the dialog?

Question

I want to use the speech to text api in android, but I don't want to be slowed down by those dialogs. Is it possible to use the functionality without them?

Yes it is possible:

You can use the SpeechRecognizer class from the API. Make sure it is used in the main thread - as required according to the API - and that your class implements the RecognitionListener.

private SpeechRecognizer speech;

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

    speech = SpeechRecognizer.createSpeechRecognizer(this);
    speech.setRecognitionListener(this);

    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
        this.getPackageName());

    speech.startListening(intent);
}

@Override
public void onBeginningOfSpeech()
{
}

@Override
public void onBufferReceived(byte[] arg0)
{
}

@Override
public void onEndOfSpeech()
{
}

@Override
public void onError(int e)
{
}

@Override
public void onEvent(int arg0, Bundle arg1)
{
}

@Override
public void onPartialResults(Bundle arg0)
{
}

@Override
public void onReadyForSpeech(Bundle arg0)
{
}

@Override
public void onResults(Bundle data)
{
    ArrayList<String> matches = data.getStringArrayList(
        SpeechRecognizer.RESULTS_RECOGNITION);

    // Do something useful with the matches =)
    // ...
}

@Override
public void onRmsChanged(float arg0)
{
}

this will recognise speech only first time, how to continuos recognising speech.... — Pradeep Sodhi, Mar 31 '14 at 06:48

You could call speech.startListening(...) again, if you defined the intent to be provided and the SpeechRecognizer within the class, instead of the onCreate method. (I'm not using speech anymore, so it's just a guess.) — Knots, Jan 13 '16 at 09:29

No.

The Intent for the speech recognition displays the dialog and there are no options to disable showing it.

You should also know that the speech recognition feature requires an internet connection so that the sound can be uploaded to Google for recognition.

What about Google API?? Does it exist as a webservice to convert audio to text? If so, is that what the Android's intent uses?? – mobibob Mar 05 '11 at 08:07
I'm pretty sure the thing about needing to connect to the internet is wrong. I turned wifi off my device and put it into wifi mode, and it still worked. If you use FREE_FORM for the RecognitionIntent, it shouldn't require internet. – FateNuller May 17 '14 at 19:21
