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");
}
@Override
public void onEndOfSpeech() {
Log.i(TAG,"onEndOfSpeech");
mStatus = "Speech ended";
}
@Override
public void onEvent(int eventType,Bundle params) {
Log.i(TAG,"onEvent " + eventType);
}
@Override
public void onPartialResults(Bundle partialResults) {
Log.i(TAG,"onPartialResults");
mStatus = "Partial results";
}
@Override
public void onReadyForSpeech(Bundle params) {
Log.i(TAG,"onReadyForSpeech");
mReady = true;
mStatus = "Speech engine ready";
}
@Override
public void onRmsChanged(float rmsdB) {
// TODO Auto-generated method stub
}
@Override
public void onError(int error) {
// TODO Auto-generated method stub
mError = "";
mStatus = "Error detected";
switch (error) {
case SpeechRecognizer.ERROR_NETWORK_TIMEOUT:
mError = " network timeout";
startListening();
break;
case SpeechRecognizer.ERROR_NETWORK:
mError = " network" ;
//toast("Please check data bundle or network settings");
return;
case SpeechRecognizer.ERROR_AUdio:
mError = " audio";
break;
case SpeechRecognizer.ERROR_SERVER:
mError = " server";
startListening();
break;
case SpeechRecognizer.ERROR_CLIENT:
mError = " client";
break;
case SpeechRecognizer.ERROR_SPEECH_TIMEOUT:
mError = " speech time out" ;
break;
case SpeechRecognizer.ERROR_NO_MATCH:
mError = " no match" ;
startListening();
break;
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
mError = " recogniser busy" ;
break;
case SpeechRecognizer.ERROR_INSUFFICIENT_PERMISSIONS:
mError = " insufficient permissions" ;
break;
}
Log.i(TAG,"Error: " + error + " - " + mError);
//startSR();
}
@Override
public void onResults(Bundle results) {
mStatus = "Got some results";
mResultAvailable = true;
String str = new String();
Log.d(TAG,"onResults " + results);
mResults = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
//mConfidences = results.getDoubleArray(SpeechRecognizer.CONFIDENCE_scoreS);
Log.i(TAG,toString());
startListening();
}
}// class Listener
public ArrayList
