Question

您好我正在使用应用程序，它始终监听语音，每一秒钟用户定时器任务，每次调用SpeechRecognizer。当我启动SpeechRecognizer时，它会发出哔哔声。请帮我删除这个。我使用过amanager.setStreamMute（AudioManager.STREAM_ALARM，true）;但这不是完美的解决方案。我的代码在这里。

    @Override
public int onStartCommand(Intent intent, int flags, int startId) {
    tts = new TextToSpeech(this, this);
    amanager = (AudioManager) getSystemService(AUDIO_SERVICE);
    startThread();

    return super.onStartCommand(intent, flags, startId);
}

public void startThread() {
    Thread thread = new Thread(this);
    thread.start();
}

public void offSound() {

    amanager.setStreamMute(AudioManager.STREAM_ALARM, true);
    amanager.setStreamMute(AudioManager.STREAM_MUSIC, true);
    amanager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
}

public void onSound() {

    amanager.setStreamMute(AudioManager.STREAM_ALARM, false);
    amanager.setStreamMute(AudioManager.STREAM_MUSIC, false);
    amanager.setStreamMute(AudioManager.STREAM_SYSTEM, false);
}

@Override
public void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
    if (null != iAudioTimer) {
        iAudioTimer.cancel();
        iAudioTimer = null;
    }
    if(tt!=null){

        tt.cancel();
        tt=null;
    }

}

public void run() {
    try {
        iAudioTimer = new Timer();
         tt = new TimerTask() {
            @Override
            public void run() {
                if (!isVoiceMatch) {
                    if (!amanager.isMusicActive()) {
                        raise();

                    }
                }

            }
        };
        iAudioTimer.schedule(tt, 0, 1 * 2000);
    } catch (Exception e) {
        Log.e("[AudioRecorder]: ", "run(): ", e);

    }
}

public void raise() {
    try {
        handler.post(new Runnable() {

            @Override
            public void run() {


                offSound();
                SpeechRecognizer speech = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
                MyRecognitionListener listener = new MyRecognitionListener();

                speech.setRecognitionListener(listener);

                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication().getPackageName());

                speech.startListening(intent);

            }
        });

    } catch (Exception e) {
        e.printStackTrace();
    }
}

class MyRecognitionListener implements RecognitionListener {

    @Override
    public void onBeginningOfSpeech() {

    }

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

    }

    @Override
    public void onEndOfSpeech() {

    }

    @Override
    public void onError(int error) {
        onSound();
    }

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

    }

    @Override
    public void onPartialResults(Bundle partialResults) {

    }

    @Override
    public void onReadyForSpeech(Bundle params) {
        onSound();
    }

    @Override
    public void onResults(Bundle results) {



    }

    @Override
    public void onRmsChanged(float rmsdB) {

    }

}

这是Android中的Google api错误，我希望Google会尽快解决此问题。

现在，您可以制作自定义标记SpeechRecogniser.SET_VOICE_FLAG = false 并为screen_on和screen_off注册接收器：

registerReceiver(trigerReceiverClass, new IntentFilter(Intent.ACTION_SCREEN_ON));
registerReceiver(trigerReceiverClass, new IntentFilter(Intent.ACTION_SCREEN_OFF));

这将有助于您删除长时间运行的进程和后台进程中的蜂鸣声，这是一种很好的做法。

有关详情，请参阅Android Speech Speech Recognition: Repeated Calling of SpeechRecognizer.startListening() fails on JB 4.1.2

当呼叫startListening时，SpeechRecognizer会发出蜂鸣声
