La reconnaissance vocale arrête d'écouter après quelques secondes

Question

J'ai beaucoup essayé mais je ne peux pas le découvrir, alors j'espère que vous pourrez m'aider.

J'essaie de créer ma propre application de reconnaissance vocale, qui n'affiche pas la boîte de dialogue.

J'ai déjà écrit du code et cela fonctionne très bien, mais mon problème est que le module de reconnaissance semble s'arrêter sans aucune erreur ou autre message dans LogCat.

Un fait étrange est que "onRmsChanged" de l'interface "RecognitionListener" est toujours appelé tout le temps, mais "onBeginningOfSpeech" n'est plus appelé.

Si je parle juste après le début de la reconnaissance vocale, cela fonctionne. Mais ce n'est pas le cas si j'attends quelques secondes.

L'API utilisée est 4.0.3 et je l'ai installée sur mon Nexus 7 avec la version 4.2.1

J'apprécierais vraiment si vous avez de bonnes idées.

Quelques extraits de code:

Ma classe:

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) + "
"; } tvOutput.setText(tvOutput.getText().toString() + "

" + "Results: " + str); } public void onRmsChanged(float rmsdB) { Log.d(TAG, "onRmsChanged()"); } }

Et ma mise en œuvre dans la 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);

Et donc ça a commencé:

srSpeechRecognizer.startListening(iSpeechIntent);

La seule solution qui permettra de contourner ce problème est d'utiliser un service tiers. 4.1.1 et 4.2 tous les deux reposent sur une version du service de reconnaissance vocale qui n'adhère pas au comportement documenté en ce que le service qui l'exécute meurt en silence.

Si vous ne souhaitez pas utiliser une API tierce et que vous devez tenir compte de cette mort de service d'une manière ou d'une autre, il est possible mais ce n'est pas joli ou idéal.

Une fois le service éteint, aucune des méthodes suivantes ne sera jamais appelée:

onBeginningOfSpeech
onError
onResults
onEndOfSpeech

Mais si onBeginningOfSpeech est appelé avant la fin du service, vous pouvez être assuré que l'onError ou onEndOfSpeech sera finalement appelé.

Par conséquent, si tout ce que vous voulez, c'est vous assurer que vous êtes informé de la vie et de la mort du service dans Jellybean la solution de contournement pour ce problème dans le SpeechRecognizer intégré est de procéder comme suit:

Créez un indicateur booléen comme isSpeechRecognizerAlive.
Chaque fois que vous démarrez SpeechRecognizer, définissez l'indicateur ci-dessus sur false.
Dans onBeginningOfSpeech, s'il est appelé, définissez isSpeechRecognizerAlive sur true.
Maintenez un gestionnaire qui, sur un délai de 4 secondes, vérifiera l'état de isSpeechRecognizerAlive. Si elle est fausse, supprimez manuellement l'instance SpeechRecognizer. Si c'est vrai, ne faites rien. Le flux normal prendra soin des choses pour vous.

Pourquoi ce n'est pas une solution idéale pour maintenir une configuration de reconnaissance vocale continue

Ce n'était pas directement indiqué dans votre question, mais quelques personnes souhaitent le faire afin de pouvoir bénéficier d'une reconnaissance vocale continue. Ce n'est pas vraiment un bon moyen de le faire dans 4.1.1 et 4.2 car le service SpeechRecognition de Google démarre maintenant avec un son "bloop" non optionnel effet. Il semble qu'il n'y ait aucun moyen de désactiver ce son. Rien n'est répertorié dans l'API pour le contrôler. Vos utilisateurs n'apprécieront PAS d'être "bloopés" sur une boucle répétée de 4 secondes.

Kaarel · Answer

Vous pouvez essayer de fournir les extras suivants RecognizerIntent :

EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS
EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS
EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS

bien qu'aucun d'entre eux ne rentre vraiment dans ce cas. Android n'offre tout simplement pas de "WAIT_UNTIL_I_START_SPEAKING "extra. Ce n'est pas un bogue (dans Jelly bean ou ailleurs), c'est simplement un manque de fonctionnalité. Et même si un tel extra est ajouté dans une future version de Android there peut ne pas être une garantie que l'application de reconnaissance vocale (telle que Google Voice Search) l'implémente réellement. La documentation RecognizerIntent contient de nombreux extras avec un comportement non spécifié.

Votre meilleure option pourrait être de relancer le module de reconnaissance dès que vous obtenez onEndOfSpeech ou onError.

Josh · Answer

J'ai créé un service doté d'un logiciel de reconnaissance audio-vocale qui simule la continuité en se redémarrant à chaque fois qu'il y a une erreur ou un résultat. Comme vous pouvez le voir, mon service écoute un récepteur de diffusion afin de démarrer/arrêter un ASR continu (c'est une batterie coûteuse, donc je vous recommande d'exécuter ce service ASR continu uniquement lorsque votre interface utilisateur pertinente est au premier plan). Les résultats de l'ASR sont également diffusés sur le reste de l'application. Vous pouvez ignorer la diffusion, le service et l'écouteur de reconnaissance sont l'idée principale. N'OUBLIEZ PAS l'autorisation INTERNET, le manifeste et la déclaration de service:

<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);

J'étais confronté au même problème pendant un certain temps et je n'ai pu trouver la bonne réponse de travail nulle part. Pour que l'écoute se produise à l'infini, postez onError() ou onResults() J'appelais à nouveau speechRecognizer.startListening(intent); après avoir réinstancié le speechRecognizer et réinitialisé l'objet d'intention.

Mais comme vous l'avez mentionné, cela finissait par s'éteindre après avoir écouté un moment.

Voici ce que j'ai essayé et cela a fonctionné pour moi.

Je me suis juste assuré qu'avant de rappeler la speechRecognizer.startListening(intent); j'appellerais

speechRecognizer.stopListening(); speechRecognizer.destroy();

et continuer à faire les choses mentionnées dans le premier paragraphe.

Jusqu'à présent, cela a bien fonctionné pour moi.
