Android 리스너 음성 인식이 호출되지 않았습니다.

Question

Android에서 SpeechRecognizer 클래스를 사용하여 음성 인식을 시도하고 RecognitionListener에 영향을 주려고합니다.

문제 : 영향을받는 수신기가 호출되지 않습니다.

private Button launchRecognition; 
private TextView textRecognised; 
private ImageView picture; 
private SpeechRecognizer sr; 
private Context context; 
private MyRecognitionListener listener; 

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

    textRecognised = (TextView) findViewById(R.id.textRecognised);

    context = this; 

    sr = SpeechRecognizer.createSpeechRecognizer(getApplicationContext()); 
    listener = new MyRecognitionListener(); 
    sr.setRecognitionListener(listener); 

    launchRecognition.setOnTouchListener(new OnTouchListener() { 

     @Override

      switch (event.getAction()) { 

      case MotionEvent.ACTION_DOWN: {

       listener.onBeginningOfSpeech(); 
       break; 
      } 

      case MotionEvent.ACTION_UP: {

    } 

    @Override

     Log.d("Speech", "onBufferReceived"); 
    } 

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

    @Override 
    public void onError(int error) { 
     Log.d("Speech", "onError" + error); 
    } 

    @Override 
    public void onEvent(int eventType, Bundle params) { 
     Log.d("Speech", "onEvent"); 
    } 

    @Override 
    public void onPartialResults(Bundle partialResults) { 
     Log.d("Speech", "onPartialResults"); 
    } 

    @Override 
    public void onReadyForSpeech(Bundle params) { 
     Log.d("Speech", "onReadyForSpeech"); 
    } 


    @Override 
    public void onResults(Bundle results) { 
     Log.d("Speech", "onResults"); 
     ArrayList strlist = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION); 
     for (int i = 0; i < strlist.size();i++) { 
      Log.d("Speech", "result=" + strlist.get(i)); 
     } 
    } 

    @Override 
    public void onRmsChanged(float rmsdB) { 
     Log.d("Speech", "onRmsChanged"); 
    } 

} 
} 

는 그것은 beginningOfSpeech()와 endOfSpeech()하지만 결코 리스너 함수를 호출 : 여기

내 주요 활동의 코드입니다.

Answer 1

이것은 당신은 당신의 MainActivity에 RecognitionListener를 구현하는 대신 시도 this class

Answer 2

같은 더 시작 물건에 대한

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
      RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH); 
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, prompt); 

체크 아웃 GAST 같은 것을 원하는

RecognizerIntent.getVoiceDetailsIntent(context)) 

를 사용하는 잘못된 Intent입니다 MyRecognitionListener를 생성합니다.

Answer 3

앱의 RECORD_AUDIO 권한이 사용 설정되어 있는지 확인하십시오.
