如何將電腦語音加載到語音識別器中？

Question

請看看在跟隨着代碼

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Speech.Recognition; 
using System.Speech.Synthesis; 
using System.Windows.Forms; 

namespace US_Speech_Recognizer 
{ 
    public class RecognizeSpeech 
    { 
     private SpeechRecognitionEngine sEngine; //Speech recognition engine 
     private SpeechSynthesizer sSpeak; //Speech synthesizer 

     public RecognizeSpeech() 
     { 
      //Make the recognizer ready 
      sEngine = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US")); 


      //Load grammar 
      Choices sentences = new Choices(); 
      sentences.Add(new string[] { "I am hungry" }); 

      GrammarBuilder gBuilder = new GrammarBuilder(sentences); 

      Grammar g = new Grammar(gBuilder); 

      sEngine.LoadGrammar(g); 

      //Add a handler 
      sEngine.SpeechRecognized +=new EventHandler<SpeechRecognizedEventArgs>(sEngine_SpeechRecognized); 

      //Ask the to speak 
      sSpeak = new SpeechSynthesizer(); 
      sSpeak.Rate = -2; 

      sSpeak.Speak("Please speak the sentence above"); 


      //Configure the recognizer to Mike 
      sEngine.SetInputToDefaultAudioDevice(); 

      sEngine.RecognizeAsync(RecognizeMode.Multiple); 
     } 

     //Start the speech recognition task 
     private void sEngine_SpeechRecognized(object sender, SpeechRecognizedEventArgs e) 
     { 
      MessageBox.Show(e.Result.Confidence.ToString()); 
     } 
    } 
} 

在這裏，我從麥克輸入加載。但是，而不是那個，我需要從計算機在sSpeak.Speak("Please speak the sentence above");內部發言中加載輸入。我怎樣才能加載這個計算機語音作爲語音識別器的輸入？請幫忙。

Answer 1

我找到了辦法

Stream stream = new MemoryStream(); 
      sSpeak.SetOutputToWaveStream(stream); 


      sSpeak.Speak("I was hungry"); 
      stream.Position = 0; 
      sSpeak.SetOutputToNull(); 


      //Configure the recognizer to stream 
      sEngine.SetInputToWaveStream(stream); 

sSpeak是SpeechSynthesizer實例。 sEngine是SpeechRecognitionEngine的實例
