範例

下列範例會辨識「在音樂類別中顯示藝術師清單」之類的片語。 此範例會 SpeechHypothesized 使用 事件，在主控台中顯示不完整的片語片段，因為辨識它們。

using System;  
using System.Speech.Recognition;  

namespace SampleRecognition  
{  
  class Program  
  {  
    static void Main(string[] args)  

    // Initialize a shared speech recognition engine.  
    {  
      using (SpeechRecognizer recognizer =  
         new SpeechRecognizer())  
      {  

        // Create a grammar.  
        //  Create lists of alternative choices.  
        Choices listTypes = new Choices(new string[] { "albums", "artists" });  
        Choices genres = new Choices(new string[] {   
          "blues", "classical", "gospel", "jazz", "rock" });  

        //  Create a GrammarBuilder object and assemble the grammar components.  
        GrammarBuilder mediaMenu = new GrammarBuilder("Display the list of");  
        mediaMenu.Append(listTypes);  
        mediaMenu.Append("in the");  
        mediaMenu.Append(genres);  
        mediaMenu.Append("category.");  

        //  Build a Grammar object from the GrammarBuilder.  
        Grammar mediaMenuGrammar = new Grammar(mediaMenu);  
        mediaMenuGrammar.Name = "Media Chooser";  

        // Attach event handlers.  
        recognizer.LoadGrammarCompleted +=  
          new EventHandler<LoadGrammarCompletedEventArgs>(recognizer_LoadGrammarCompleted);  
        recognizer.SpeechRecognized +=  
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);  
        recognizer.SpeechHypothesized +=   
          new EventHandler<SpeechHypothesizedEventArgs>(recognizer_SpeechHypothesized);  

        // Load the grammar object to the recognizer.  
        recognizer.LoadGrammarAsync(mediaMenuGrammar);  

        // Keep the console window open.  
        Console.ReadLine();  
      }  
    }  

    // Handle the SpeechHypothesized event.  
    static void recognizer_SpeechHypothesized(object sender, SpeechHypothesizedEventArgs e)  
    {  
      Console.WriteLine("Speech hypothesized: " + e.Result.Text);  
    }  

    // Handle the LoadGrammarCompleted event.  
    static void recognizer_LoadGrammarCompleted(object sender, LoadGrammarCompletedEventArgs e)  
    {  
      Console.WriteLine("Grammar loaded: " + e.Grammar.Name);  
    }  

    // Handle the SpeechRecognized event.  
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)  
    {  
      Console.WriteLine("Speech recognized: " + e.Result.Text);  
    }  
  }  
}  

備註

當輸入模棱兩可時，共用辨識器可以引發此事件。 例如，針對支援辨識「新遊戲請」或「新遊戲」的語音辨識文法，「新遊戲請」是明確的輸入，而「新遊戲」則是模棱兩可的輸入。
