Question

我想听用户说的第一个字。语音识别开始时，我会听到两声，但是立即听到停止音。我观察到onRMSchanged是发生事情的唯一方法。

这就是我使用SpeechRecognizer的方式。运行应用程序时，我已连接到互联网。

        Intent speechintent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        speechintent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS , 1000);
        speechintent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,  RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        speechintent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en");

        SpeechRecognizer speechRecognizer = SpeechRecognizer.createSpeechRecognizer(Inference.getmContext());
        speechRecognizer.setRecognitionListener(new RecognitionListener() {
            @Override
            public void onReadyForSpeech(Bundle params) {

            }

            @Override
            public void onBeginningOfSpeech() {
            Log.i("beg", "beg");
            }

            @Override
            public void onRmsChanged(float rmsdB) {
                Log.i("on rms changed", "rms changed");
            }

            @Override
            public void onBufferReceived(byte[] buffer) {
                Log.i("ANSWER","END");
            }

            @Override
            public void onEndOfSpeech() {
                Log.i("ANSWER","END");
            }

            @Override
            public void onError(int error) {

            }

            @Override
            public void onResults(Bundle results) {

               Log.i("ANSWER",results.getString(RecognizerIntent.EXTRA_RESULTS));
                ArrayList<String> result = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);

            }

            @Override
            public void onPartialResults(Bundle partialResults) {
                Log.i("ANSWER",partialResults.getString(RecognizerIntent.EXTRA_RESULTS));
            }

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

            }
        });

        speechRecognizer.startListening(speechintent);
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                speechRecognizer.stopListening();
            }
        }, 1000);

我不知道为什么它不让我说话。

更新：

这是方法执行的顺序：

onRmsChanged
onReadyForSpeech
onError

onError我得到了错误代码2，表示网络错误，但是我已经将Google文本设置为语音，我在清单中设置了INTERNET和RECORD_AUDIO权限，并且已连接到Internet。我不明白怎么了？

语音识别立即停止收听
