[英]How to increase the amount of time to consider input complete, in android voice recognition?
[英]How to increase the voice listen time in Google Recognizer Intent(Speech Recognition) Android
我确实尝试给毫秒以下这些额外的时间
Recognizer Intent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS
Recognizer Intent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS
Recognizer Intent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS
但不会影响语音收听时间! 我现在获得的语音收听时间仅为3秒! 我如何获得10秒的聆听时间
似乎它仅适用于以下ICS: https : //stackoverflow.com/a/17675098/9427932
但是您总是可以通过创建自己的类并继承SpeechRecognizer来自定义Google语音,我在Xamarin Android上编写了这些代码,因此它与android非常相似:
public class CustomRecognizer : Java.Lang.Object, IRecognitionListener, TextToSpeech.IOnInitListener
{
private SpeechRecognizer _speech;
private Intent _speechIntent;
public string Words;
public CustomRecognizer(Context _context)
{
this._context = _context;
Words = "";
_speech = SpeechRecognizer.CreateSpeechRecognizer(this._context);
_speech.SetRecognitionListener(this);
_speechIntent = new Intent(RecognizerIntent.ActionRecognizeSpeech);
_speechIntent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm);
_speechIntent.PutExtra(RecognizerIntent.ActionRecognizeSpeech, RecognizerIntent.ExtraPreferOffline);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputCompleteSilenceLengthMillis, 1000);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputPossiblyCompleteSilenceLengthMillis, 1000);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputMinimumLengthMillis, 1500);
}
void startover()
{
_speech.Destroy();
_speech = SpeechRecognizer.CreateSpeechRecognizer(this._context);
_speech.SetRecognitionListener(this);
_speechIntent = new Intent(RecognizerIntent.ActionRecognizeSpeech);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputCompleteSilenceLengthMillis, 1000);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputPossiblyCompleteSilenceLengthMillis, 1000);
_speechIntent.PutExtra(RecognizerIntent.ExtraSpeechInputMinimumLengthMillis, 1500);
StartListening();
}
public void StartListening()
{
_speech.StartListening(_speechIntent);
}
public void StopListening()
{
_speech.StopListening();
}
public void OnBeginningOfSpeech()
{
}
public void OnBufferReceived(byte[] buffer)
{
}
public void OnEndOfSpeech()
{
}
public void OnError([GeneratedEnum] SpeechRecognizerError error)
{
Words = error.ToString();
startover();
}
public void OnEvent(int eventType, Bundle @params)
{
}
public void OnPartialResults(Bundle partialResults)
{
}
public void OnReadyForSpeech(Bundle @params)
{
}
public void OnResults(Bundle results)
{
var matches = results.GetStringArrayList(SpeechRecognizer.ResultsRecognition);
if (matches == null)
Words = "Null";
else
if (matches.Count != 0)
Words = matches[0];
else
Words = "";
//do anything you want for the result
}
startover();
}
public void OnRmsChanged(float rmsdB)
{
}
public void OnInit([GeneratedEnum] OperationResult status)
{
if (status == OperationResult.Error)
txtspeech.SetLanguage(Java.Util.Locale.Default);
}}
您可以调用startover()在结束后立即开始录制,因此看起来像是“连续语音”(在您的情况下为10秒)
