SpeechRecognitionEngine.AudioSignalProblemOccurred 事件

定義

SpeechRecognitionEngine 偵測到音訊訊號問題時引發。

public:
 event EventHandler<System::Speech::Recognition::AudioSignalProblemOccurredEventArgs ^> ^ AudioSignalProblemOccurred;
public event EventHandler<System.Speech.Recognition.AudioSignalProblemOccurredEventArgs> AudioSignalProblemOccurred;
member this.AudioSignalProblemOccurred : EventHandler<System.Speech.Recognition.AudioSignalProblemOccurredEventArgs> 
Public Custom Event AudioSignalProblemOccurred As EventHandler(Of AudioSignalProblemOccurredEventArgs) 

事件類型

範例

下列範例會定義可收集事件相關資訊的 AudioSignalProblemOccurred 事件處理常式。

private SpeechRecognitionEngine recognizer;  

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

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

// Gather information when the AudioSignalProblemOccurred event is raised.  
void recognizer_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.  
}  

備註

若要取得發生的問題,請使用 AudioSignalProblem 相關聯 AudioSignalProblemOccurredEventArgs 之 的 屬性。

當您建立 AudioSignalProblemOccurred 委派 (Delegate) 時,就可以識別即將處理此事件的方法。 若要使事件與您的事件處理常式產生關聯,請將委派的執行個體 (Instance) 加入至事件。 除非您移除委派,否則每當事件發生時就會呼叫事件處理常式。 如需事件處理常式委派的詳細資訊,請參閱 事件和委派
