问题描述

我碰巧遇到了这个随机问题... 以下是我的代码

mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(mContext);
        initializeRecognitionListener();
        mSpeechRecognizer.setRecognitionListener(mRecognitionListener);

    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                    RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US");
            intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, Long.valueOf(3000L));
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
    mSpeechRecognizer.startListening(intent);

方法InitializeRecognitionListener()：

private void initializeRecognitionListener() {
    mRecognitionListener = new RecognitionListener() {

    @Override        
    public void onReadyForSpeech(Bundle params) {
        Log.d("onReadyForSpeech()", "onReadyForSpeech!");
        isRecognizing = true;
    }

    @Override
    public void onBeginningOfSpeech() {
        Log.d("onBeginningOfSpeech()", "onBeginningOfSpeech!");

    }

    @Override
    public void onEndOfSpeech() {
        Log.e("onEndOfSpeech()", "onEndOfSpeech! stop SCO");
    }
     ... 
}

主要问题是"onReadyForSpeech()"和"onBeginningOfSpeech()"方法有时在mSpeechRecognizer.startListening(Intent)之后不调用。此外，也不能调用"onEndOfSpeech()"。

我使用的是Nexus 4和Android 4.2.2
