安卓语音识别3次后停止

Question

首先对不起我的英语，我的母语是西班牙语

我遵循这个主题，通过Android语音识别服务在后台实现语音识别；4.2以及如何使谷歌语音在安卓的后台持续运行

在我的代码中，everithing是有效的，但当我单独说3个单词时，服务不会听更多的单词或命令。

我怎么还能检测到更多的命令？

case MSG_RECOGNIZER_START_LISTENING：

            if (Build.VERSION.SDK_INT >= 16);//Build.VERSION_CODES.JELLY_BEAN)
            {

                target.mAudioManager.setStreamMute(AudioManager.STREAM_SYSTEM, true);
            }
             if (!target.mIsListening)
             {
                mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(this);
               mSpeechRecognizer.setRecognitionListener(new SpeechRecognitionListener());
               mSpeechRecognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
               mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                                 RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
               mSpeechRecognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                                 this.getPackageName());

                 target.mSpeechRecognizer.startListening(target.mSpeechRecognizerIntent);
                 target.mIsListening = true;
