Android speech Recognition App Without Pop Up

Question

I\'m currently looking into getting a career with JAVA and have decided to start by building an app. I have this code right here that I am using to trigger Speech Recognitio

Answer 1

It's been a long time since the post. Still for those who are looking, the above code provided by Hoan is almost complete, but there is an important line missing. Both in question and answer and I am not sure how it could work without that.

You need to create the SpeechRecognitionListener and set it as a listener for the SpeechRecognizer. Also it has to be done before we make a call to startListening() method of the SpeechRecognizer.

SpeechRecognitionListener listener = new SpeechRecognitionListener(); mSpeechRecognizer.setRecognitionListener(listener);

Then you also need to remove the listener from the onError event.

AndroidManifest.xml

Add the following permission:

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

class members

private SpeechRecognizer mSpeechRecognizer;
private Intent mSpeechRecognizerIntent; 
private boolean mIslistening; 

In onCreate

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    .........
    .........
    mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
    mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                                     RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                                     this.getPackageName());


    SpeechRecognitionListener listener = new SpeechRecognitionListener();
    mSpeechRecognizer.setRecognitionListener(listener);

}   

in your button listener just use this code

if (!mIsListening)
{
    mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
}

In onDestroy

if (mSpeechRecognizer != null)
{
        mSpeechRecognizer.destroy();
}

Inside your activity create the inner class

protected class SpeechRecognitionListener implements RecognitionListener
{

    @Override
    public void onBeginningOfSpeech()
    {               
        //Log.d(TAG, "onBeginingOfSpeech"); 
    }

    @Override
    public void onBufferReceived(byte[] buffer)
    {

    }

    @Override
    public void onEndOfSpeech()
    {
        //Log.d(TAG, "onEndOfSpeech");
     }

    @Override
    public void onError(int error)
    {
         mSpeechRecognizer.startListening(mSpeechRecognizerIntent);

        //Log.d(TAG, "error = " + error);
    }

    @Override
    public void onEvent(int eventType, Bundle params)
    {

    }

    @Override
    public void onPartialResults(Bundle partialResults)
    {

    }

    @Override
    public void onReadyForSpeech(Bundle params)
    {
        Log.d(TAG, "onReadyForSpeech"); //$NON-NLS-1$
    }

    @Override
    public void onResults(Bundle results)
    {
        //Log.d(TAG, "onResults"); //$NON-NLS-1$
        ArrayList<String> matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        // matches are the return values of speech recognition engine
        // Use these values for whatever you wish to do
    }

    @Override
    public void onRmsChanged(float rmsdB)
    {
    }
}

Answer 3

I ran into that issue as well. It seems like having startActivityForResult(...) will enable the pop-up mic, then you can handle the response in onActivityResult(). However, simply adding that startActivityForResult messed up my startListening(mSpeechRecognizerIntent), so you may need to do more adjustment.

mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                                     RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                                     this.getPackageName());
startActivityForResult(recognizerIntent, 100);

// call back
onActivityResult(int requestCode, int resultCode, Intent data){...}

Don't Forget to add permission of following:-

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