私は認識のためのプロジェクトを持っています。それは機能しますが、このプロジェクトをどのようにクラスとして使用し、そのメソッドを他のクラスから呼び出すと、オンラインで例外の問題が発生します:
sre = new SpeechRecognitionEngine(ri.Id);
エラーは次のとおりです。
必要な ID の認識エンジンが見つかりません。
コード：
KinectAudioSource source = kinectSensor.AudioSource;
source.EchoCancellationMode = EchoCancellationMode.None; // No AEC for this sample
source.AutomaticGainControlEnabled = false; // Important to turn this off for speech recognition
// source.SystemMode = SystemMode.OptibeamArrayOnly;
speechRecognizer = CreateSpeechRecognizer();
using (Stream s = source.Start())
{
speechRecognizer.SetInputToAudioStream(s, new SpeechAudioFormatInfo(EncodingFormat.Pcm, 16000, 16, 1, 32000, 2, null));
Console.WriteLine("Recognizing speech. Say: 'purple', 'green' or 'blue'. Press ENTER to stop");
speechRecognizer.RecognizeAsync(RecognizeMode.Multiple);
Console.ReadLine();
Console.WriteLine("Stopping recognizer ...");
speechRecognizer.RecognizeAsyncStop();
}
private static SpeechRecognitionEngine CreateSpeechRecognizer()
{
RecognizerInfo ri = GetKinectRecognizer();
SpeechRecognitionEngine sre;
//if (ri == null) return 0;
sre = new SpeechRecognitionEngine(ri.Id);
var colors = new Choices();
colors.Add("red");
colors.Add("green");
colors.Add("blue");
var gb = new GrammarBuilder { Culture = ri.Culture };
gb.Append(colors);
// Create the actual Grammar instance, and then load it into the speech recognizer.
var g = new Grammar(gb);
sre.LoadGrammar(g);
sre.SpeechRecognized += SreSpeechRecognized;
sre.SpeechHypothesized += SreSpeechHypothesized;
sre.SpeechRecognitionRejected += SreSpeechRecognitionRejected;
return sre;
}
private static RecognizerInfo GetKinectRecognizer()
{
Func<RecognizerInfo, bool> matchingFunc = r =>
{
string value;
r.AdditionalInfo.TryGetValue("Kinect", out value);
return "True".Equals(value, StringComparison.InvariantCultureIgnoreCase) && "en-US".Equals(r.Culture.Name, StringComparison.InvariantCultureIgnoreCase);
};
return SpeechRecognitionEngine.InstalledRecognizers().Where(matchingFunc).FirstOrDefault();
}
