Android - 语音文字不停地沉默

Question

我尝试用语音来发短信。 this link没问题，但我不想调用意图并使用对话框。

我创建了一个语音识别器实例，它会监听意图。

SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer(getContext());
sr.setRecognitionListener(new RecognitionListener() {
        @Override
        public void onResults(Bundle b) {
            Log.i("TAG", " onResults "); }
        @Override
        public void onBeginningOfSpeech() {
            Log.i("TAG", " onBeginningOfSpeech ");
        }@Override
        public void onRmsChanged(float rmsdB) {
            Log.i("TAG" , " onRmsChanged " + rmsdB);
        }
        @Override
        ....

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
            RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
sr.startListening(intent);

当我运行此代码时，onRmsChanged会多次触发。所以我评论Log.i("TAG" , " onRmsChanged " + rmsdB);。

onReadyForSpeech - ＆gt; onBeginningOfSpeech - ＆gt; onEndOfSpeech - ＆gt; onResults。但是超时太短了。 现在，我想在沉默中等待一段时间。我能怎么做？它应该听，直到我拨打sr.stoplistening()
