语音识别器stoppllistening()不工作



我目前有一个语音识别器听声音,它是通过一个按钮激活,分别切换startListening()和stoppllistening()。我的问题是,stoppllistening()实际上并没有在第一次之后停止语音识别器。当使用按钮激活和关闭语音识别器时,您可以清楚地听到不同的声音。然而,在第一次调用stoppllistening()之后(它成功了),结束声音不会产生,它结束的唯一方式是超时。

我创建的语音识别器如下:

mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
        mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3);
        mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                this.getPackageName());
        mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
        mSpeechRecognizer.setRecognitionListener(this); 

我重写了所有必要的方法:

@Override
    public void onReadyForSpeech(Bundle params) {
        Log.i(TAG, "Ready for speech input");
    }
    @Override
    public void onBeginningOfSpeech() {
        mIsEndOfSpeech = false;
        Log.i(TAG, "Speech beginning");
    }
    @Override
    public void onRmsChanged(float rmsdB) {
        Log.i(TAG, "Speech RMS Changed: " + rmsdB);
    }
    @Override
    public void onBufferReceived(byte[] buffer) {
        Log.i(TAG, "Speech buffer received: " + buffer.toString());
    }
    @Override
    public void onEndOfSpeech() {
        mIsEndOfSpeech = true;
        Log.i(TAG, "Speech recognition ended");
    }
    @Override
    public void onError(int error) {
        Log.e(TAG, "Speech recognition error: " + error);
    }
    @Override
    public void onResume() {
        super.onResume();
    }
    @Override
    protected void onPause() {
        super.onPause();
        if (mSpeechRecognizer != null) {
            mSpeechRecognizer.destroy();
            Log.i(TAG, "Speech destroy");
        }
    }
    @Override
    public void onResults(Bundle results) {
        Log.i(TAG, "Speech recognition results received");
        ArrayList<String> matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
    }
    @Override
    public void onPartialResults(Bundle partialResults) {
        Log.i(TAG, "Speech recognition partial results received");
    }
    @Override
    public void onEvent(int eventType, Bundle params) {
        Log.i(TAG, "Speech recognition event called: " + eventType);
    }

我的问题在于调用startListening()和stoppllistening()的第一次尝试成功。然而,在此之后的任何尝试,stoppllistening()都不起作用,它必须超时才能结束。我注意到的一件事是,在LogCat中,它声明'不能在没有startListening()之前调用stoppllistening(),即使startListening()已经被调用。

假设Google是您默认的识别服务提供商,当前版本的Google 'Now' stopListening()无法正常工作。
