Voice recognition stops listening after a few seconds

I tried a lot, but I can not find it, so I hope you can help me.

I am trying to create my own voice recognition application that does not display a dialog.

I already wrote the code and it works very well, but my problem is that the recognizer seems to stop without any errors or other interference in LogCat.

The strange fact is that "onRmsChanged" from the "RecognitionListener" interface is still called all the time, but "onBeginningOfSpeech" is no longer called.

If I speak right after the start of speech recognition, it works. But this is not the case if I wait a few seconds.

Used API 4.0.3 and I installed it on my Nexus 7 with version 4.2.1

I would really appreciate it if you have any good ideas.

Some snippets of code:

My class:

class SpeechListener implements RecognitionListener { public void onBeginningOfSpeech() { Log.d(TAG, "onBeginningOfSpeech()"); } public void onBufferReceived(byte[] buffer) { Log.d(TAG, "onBufferReceived()"); } public void onEndOfSpeech() { Log.d(TAG, "onEndOfSpeech()"); } public void onError(int error) { Log.d(TAG, "onError(): " + error); if(error == SpeechRecognizer.ERROR_NO_MATCH) { } else if(error == SpeechRecognizer.ERROR_SPEECH_TIMEOUT) { } else { tvOutput.setText("Error: " + error); } } public void onEvent(int eventType, Bundle params) { Log.d(TAG, "onEvent()"); } public void onPartialResults(Bundle partialResults) { Log.d(TAG, "onPartialResults()"); } public void onReadyForSpeech(Bundle params) { Log.d(TAG, "onReadyForSpeech()"); } public void onResults(Bundle results) { Log.d(TAG, "onResults(): " + results); String str = new String(); ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); for(int i = 0; i < data.size(); i++) { str += data.get(i) + "\n"; } tvOutput.setText(tvOutput.getText().toString() + "\n\n" + "Results: " + str); } public void onRmsChanged(float rmsdB) { Log.d(TAG, "onRmsChanged()"); } }

And my implementation in MainActivity:

  this.srSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this); this.srSpeechRecognizer.setRecognitionListener(new SpeechListener()); this.iSpeechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "voice.recognition.test"); this.iSpeechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);

And so it began:

 srSpeechRecognizer.startListening(iSpeechIntent);

The only solution that is likely to circumvent this problem is to use a third-party service. 4.1.1 and 4.2 both rely on a version of the speech recognition service that does not stick to the documented behavior in that the service that works with it dies silently.

If you do not want to use a third-party API, and you need to somehow take into account this death of the service, this is possible, but it is not very or ideal.

Once the service dies, none of the following methods will ever be called:

  • onBeginningOfSpeech
  • onError
  • onResults
  • onEndOfSpeech

But if the onBeginningOfSpeech call is called before the service dies, you can be sure that either onError or onEndOfSpeech will be called in the end.

Therefore, if all you want is to be sure that you are aware of the life and death of the service in Jellybean , the workaround for this problem in the built-in SpeechRecognizer is as follows:

  • Create a boolean flag like isSpeechRecognizerAlive.
  • Each time you start SpeechRecognizer, set the flag above to false.
  • In onBeginningOfSpeech, if called, set isSpeechRecognizerAlive to true.
  • It supports a handler that checks the status of isSpeechRecognizerAlive at a 4-second delay. If this is false, manually destroy the SpeechRecognizer instance. If is is true, do nothing. A normal flow will take care of you.

Why is this not the ideal solution to maintain constant speech recognition?

This was not explicitly stated in your question, but some people want to do this in order to be able to continuously recognize speech. This is not a good way to do this in 4.1.1 and 4.2, because the Google SpeechRecognition service now starts with a non-standard “bloop” sound effect. There seems to be no way to mute this sound. There is nothing in the API to manage it. Your users DON'T GET to be “bloated” on a 4 second loop repeating.

You can try to provide the following RecognizerIntent additional functions:

  • EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS
  • EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS
  • EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS

although none of them really fit in this case. Android simply does not offer " WAIT_UNTIL_I_START_SPEAKING " additionally. This is not a mistake (in Bean jelly or anywhere else), it is simply the lack of a function. And even if such an additional feature is added to a future version of Android, there can be no guarantee that a speech recognition application (for example, Google Voice Search) really does. The RecognizerIntent documentation contains many additional features with unspecified behavior.

A better option would be to restart the resolver as soon as you get onEndOfSpeech or onError .

I made a Service that wears Audio to Speech Recognizer, which simulates continuity, rebooting itself every time there is an error or result. , , / ASR ( , ASR , ). ASR . , Recognizer - . DONT INTERNET :

 <service android:name=".speechRecognitionService" />

SpeechRecognitionService:

  /** * Created by Josh on 22/07/15. * This service bears an Audio to Speech recognizer (ASR), once this service is started, * it listens a broadcast called "asrService". * the Service starts ASR when it receives a "START-ASR" value inside the "message" parameter of its broadcast receiver * the Service stopss ASR when it receives a "STOP-ASR" value inside the "message" parameter of its broadcast receiver Example: Intent intent = new Intent("asrService"); intent.putExtra("message", "STOP-ASR"); LocalBroadcastManager.getInstance(context).sendBroadcast(intent); Once the ASR Listener that this service bears is running, it will broadcast the results is gets. To catch ASR results, implement a Broadcast receiver that listens to app.asrResult="ASRresult", for example: private BroadcastReceiver ASRReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String message = intent.getStringExtra("message"); if(message!=null) { app.logwhite("ASR says: "+message); } } }; LocalBroadcastManager.getInstance(this).registerReceiver(ASRReceiver, new IntentFilter(app.asrResult)); Unregister the broadcast receiver likewise: LocalBroadcastManager.getInstance(this).unregisterReceiver(ASRReceiver);
