示例

以下示例附加语音识别器 、 SpeechHypothesizedSpeechRecognized和 SpeechRecognitionRejected 事件的处理程序。 这三个事件的事件参数类型都派生自 RecognitionEventArgs，后者用作处理程序中的事件数据参数。

// Initialize the speech recognizer.  
private void Initialize(SpeechRecognitionEngine recognizer)  
{  
  // Attach handlers for the SpeechHypothesized, SpeechRecognitionRejected,  
  // and SpeechRecognized events.  
  recognizer.SpeechHypothesized +=  
    new EventHandler<SpeechHypothesizedEventArgs>(DisplayResult);  
  recognizer.SpeechRecognitionRejected +=  
    new EventHandler<SpeechRecognitionRejectedEventArgs>(DisplayResult);  
  recognizer.SpeechRecognized +=  
    new EventHandler<SpeechRecognizedEventArgs>(DisplayResult);  

  // Add other initialization code here.  
}  

// Handle the SpeechHypothesized, SpeechRecognitionRejected,  
// and SpeechRecognized events.  
private void DisplayResult(object sender, RecognitionEventArgs e)  
{  
  if (e is SpeechHypothesizedEventArgs)  
  {  
    Console.WriteLine("Speech hypothesized:");  
  }  
  else if (e is SpeechRecognitionRejectedEventArgs)  
  {  
    Console.WriteLine("Speech recognition rejected:");  
  }  
  else if (e is SpeechRecognizedEventArgs)  
  {  
    Console.WriteLine("Speech recognized:");  
  }  

  // Add code to handle the event.  
}

注解

属性 Result 以 对象的形式 RecognitionResult 获取识别信息。 有关语音识别事件的详细信息，请参阅 使用语音识别事件。

RecognitionEventArgs 是以下类的基础：

RecognitionEventArgs 派生自 EventArgs。

属性

Result

确定指定对象是否等于当前对象。

(继承自 Object)
GetHashCode()

作为默认哈希函数。

(继承自 Object)
GetType()

获取当前实例的 Type。

(继承自 Object)
MemberwiseClone()

创建当前 Object 的浅表副本。
