android - SpeechRecognizer 突然无法离线工作

Question

SpeechRecognizer 正常工作了很长时间，突然它不工作了，现在没有检测到任何东西.. 示例代码是这样的。当它在线时它可以正常工作但离线时不能，我错过了吗什么地方都有？？？

    SpeechRecognizer speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
    Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
    speechRecognizer.setRecognitionListener(new RecognitionListener() {
        @Override
        public void onReadyForSpeech(Bundle params) {

        }

        @Override
        public void onBeginningOfSpeech() {

        }

        @Override
        public void onRmsChanged(float rmsdB) {

        }

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

        }

        @Override
        public void onEndOfSpeech() {
            //speechRecognizer.stopListening();
        }

        @Override
        public void onError(int error) {

        }

        @Override
        public void onResults(Bundle results) {
            List<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
            String full = data.get(0);
            System.out.println(full);
        }

        @Override
        public void onPartialResults(Bundle partialResults) {

        }

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

        }
    });
    speechRecognizer.startListening(i);`

默认情况下，语音识别仅在线工作。识别过程需要大量的内存分配，如果你想要一个离线引擎，你应该避免使用默认的Android识别服务。
