我正在使用Android的语音API来不断获取用户的输入.但是,当发生错误时,这不能很好地工作.

我所做的是在检测错误的方法中重新启动监听器.它有时会工作,但识别器会经常挂起一段时间.特别是在检测到服务器,网络超时和识别器忙碌错误后.这很烦人！

我找到了一些解决这个问题的尝试,但没有一个能为我工作.

你有更好的主意吗？

这是我的代码：

private void startSR(){

    intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    //intent.putExtra(RecognizerIntent.,value)
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,mContext.getPackageName());

    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,10);

    Log.d(TAG,"Speech recognition started!");
    if (recognizer != null) {
        recognizer = null;
        mListener = null;
    }

    Log.d(TAG,"setRecognitionListener");
    recognizer = SpeechRecognizer.createSpeechRecognizer(mContext);
    mListener = new Listener();

    recognizer.setRecognitionListener(mListener);

    recognizer.startListening(intent);

}
class Listener implements RecognitionListener{

    @Override
    public void onBeginningOfSpeech() {
        Log.i(TAG,"onBeginningOfSpeech");
        mStatus = "Beginning speech";
    }

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

    }

        Log.i(TAG,"onEndOfSpeech");
        mStatus = "Speech ended";
    }
