音频识别问题 [英] Problem with Audio Recognition

问题描述

我有一个认可项目。它可以工作，但如果我使用这个项目如何一个类，并从其他类调用其方法我有一个问题与线上的异常   sre
= new
SpeechRecognitionEngine （ ri 。 Id ）; ：

无识别者找到所需的ID。

 KinectAudioSource source = kinectSensor.AudioSource; source.EchoCancellationMode = EchoCancellationMode.None; //此示例源没有AEC .AutomaticGainControlEnabled = false; //重要的是关闭它以进行语音识别// 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（"识别语音。说：'紫色'，'绿色'或'蓝色'。按ENTER键停止'）; speechRecognizer.RecognizeAsync（RecognizeMode.Multiple）;到Console.ReadLine（）; Console.WriteLine（"Stopping Recognizer ..."）; speechRecognizer.RecognizeAsyncStop（）; } 

 private static SpeechRecognitionEngine CreateSpeechRecognizer（）{RecognizerInfo ri = GetKinectRecognizer（）; SpeechRecognitionEngine sre; // if（ri == null）返回0; sre = new SpeechRecognitionEngine（ri.Id）; var colors = new Choices（）; colors.Add（QUOT;红色"）; colors.Add（QUOT;绿色"）; colors.Add（QUOT;蓝色"）; var gb = new GrammarBuilder {Culture = ri.Culture}; gb.Append（颜色）; //创建实际的语法实例，然后将其加载到语音识别器中。 var g = new Grammar（gb）; sre.LoadGrammar（克）; sre.SpeechRecognized + = SreSpeechRecognized; sre.SpeechHypothesized + = SreSpeechHypothesized; sre.SpeechRecognitionRejected + = SreSpeechRecognitionRejected;返回sre; } 

 private static RecognizerInfo GetKinectRecognizer（）{Func< RecognizerInfo，bool> matchingFunc = r => {                字符串值; 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（）; }

异常的类型是什么

你可以解释一下

I have a project for recognition. It works, but if i use this project how a class and call its methods from other class i have a problem with exception on line  sre = new SpeechRecognitionEngine(ri.Id); :

No recognizer of the required ID found.

   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();        }
