Android语音超时-语音识别

Question

我正在构建一个通过语音识别收集用户数据的应用程序。我的问题是，在调用语音超时错误之前，只需大约5秒，就可以阻止语音识别器识别任何其他声音。我的问题是：，如何增加超时错误的时间，或者如何停止错误。

我的代码：

SpeechRecogniser sr = createSpeechRecogniser(this)
recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE,"en");

recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 3);

sr.startListening(recogniserIntent);
sr.setOnRecognitionListener(new OnRecognitionListener(){
    //implenent all its methods
    onError(int code){
        switch(code){
            case ERROR_SPEECH_TIMEOUT:
            //this is where the error is called and stops the speech recogniser
            //i want the time for this error to be increased
            break;

            }
        }
});

这些可选参数有助于延长时间，如果需要超出(服务通过此参数尊重的时间有限制)，则必须覆盖stackoverflow.com. you /a/49810988/806328中的识别器侦听器。

recognizerIntent.putExtra(RecognizerIntent.ACTION_RECOGNIZE_SPEECH, RecognizerIntent.EXTRA_PREFER_OFFLINE);
            recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, 1000);
            recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS, 1000);
            recognizerIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 1500);
