範例

下列範例會辨識「在音樂類別中顯示藝人清單」或「顯示相簿」等片語。 此範例會使用 事件的處理常式 SpeechRecognitionRejected ,在語音輸入無法與文法內容相符時,在主控台中顯示通知,且有足夠的信心來產生成功的辨識。

namespace SampleRecognition

    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 genres = new Choices(new string[] {   
          "blues", "classical", "gospel", "jazz", "rock" });  

        //  Create a GrammarBuilder object and assemble the grammar components.

    // 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)

  }  
}  

備註

事件 SpeechRecognitionRejected 是由 SpeechRecognizerSpeechRecognitionEngine 類別引發。

當辨識作業中沒有任何替代專案具有足以接受的信賴分數時,語音辨識引擎會產生SpeechRecognitionRejected事件。 可透過 Result 屬性取得拒絕片語的詳細資訊。

SpeechRecognitionRejectedEventArgs 衍生自 RecognitionEventArgs

屬性

Result

取得與語音辨識事件關聯的辨識結果資料。
