示例

以下示例定义一个事件处理程序，用于收集有关事件 AudioSignalProblemOccurred 的信息。

private SpeechRecognitionEngine sre;  

// Initialize the speech recognition engine.  
private void Initialize()  
{  
  sre = new SpeechRecognitionEngine();  

  // Add a handler for the AudioSignalProblemOccurred event.  
  sre.AudioSignalProblemOccurred += new EventHandler<AudioSignalProblemOccurredEventArgs>(sre_AudioSignalProblemOccurred);  
}  

// Gather information when the AudioSignalProblemOccurred event is raised.  
void sre_AudioSignalProblemOccurred(object sender, AudioSignalProblemOccurredEventArgs e)  
{  
  StringBuilder details = new StringBuilder();  

  details.AppendLine("Audio signal problem information:");  
  details.AppendFormat(  
    " Audio level:               {0}" + Environment.NewLine +  
    " Audio position:            {1}" + Environment.NewLine +  
    " Audio signal problem:      {2}" + Environment.NewLine +  
    " Recognition engine audio position: {3}" + Environment.NewLine,  
    e.AudioLevel, e.AudioPosition, e.AudioSignalProblem,  
    e.recoEngineAudioPosition);  

  // Insert additional event handler code here.  
}  

注解

当 AudioSignalProblemOccurredEventArgs.AudioSignalProblem 或 SpeechRecognizer 引发AudioSignalProblemOccurred事件时， SpeechRecognitionEngine 属性获取此枚举的成员。
