Hack for EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS?

Question

I'm working on an android app, that offers continuous Speech Recognition.

Everything works fine except the silence delay after last word pronounced which is around 6 seconds.

I have seen that it's a known bug in Android, but is there any alternatives / hacks / workaround for this ?

Intent intent = new Intent (RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

intent.putExtra (RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, Locale.getDefault ());
intent.putExtra (RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
intent.putExtra (RecognizerIntent.EXTRA_CONFIDENCE_SCORES, true);
intent.putExtra (RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, 0);
intent.putExtra (RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS, 0);
intent.putExtra (RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication ().getPackageName ());

speechRecognizer.startListening (intent);

So basically RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS is not taken into consideration at all.

Is there any way to solve this ? or an alternative API ? (I have used PocketSphinx but couldn't make it work for sentences and words outside the dictionary).

I suggest trying this:

mNoSpeechCountDown = new CountDownTimer(COUNT, COUNT) {

        @Override
        public void onTick(long l) {

        }

        @Override
        public void onFinish() {
            Log.v(TAG, "CountDown Finished");
            processResults(mResult + ' ' + mPartialResult);
            mListener.restartListener();

        }
    };
    mNoSpeechCountDown.start();

}

and restarting the countdown on every onPartial of course this requires you to implement your own RecognitionListener.

ContinuousRecognizer implements RecognitionListener

Thanks. However there is no guarantee that `onPartial` returns something.. in fact it never did for me. — , Aug 13 '16 at 13:37
recognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1); recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true); it always does for me this way which android version are you running ? — ketrox, Aug 13 '16 at 13:38
from the docs : `The server may ignore a request for partial * results in some or all cases.` — , Aug 13 '16 at 13:45
since it seems that it's the only way, I'll ignore the warning on the doc and go with it. Thanks :) — , Aug 13 '16 at 18:35
