SpeechRecognitionEngine.AudioSignalProblemOccurred SpeechRecognitionEngine.AudioSignalProblemOccurred SpeechRecognitionEngine.AudioSignalProblemOccurred SpeechRecognitionEngine.AudioSignalProblemOccurred Event

定義

SpeechRecognitionEngine がオーディオ信号の問題を検出したときに発生します。Raised when the SpeechRecognitionEngine detects a problem in the audio signal.

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) 

次の例は、に関する情報を収集するイベント ハンドラーを定義、AudioSignalProblemOccurredイベント。The following example defines an event handler that gathers information about an AudioSignalProblemOccurred event.

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.  
}  

注釈

どのような問題が発生させるには、使用、AudioSignalProblemプロパティ、関連付けられているAudioSignalProblemOccurredEventArgsします。To get which problem occurred, use the AudioSignalProblem property of the associated AudioSignalProblemOccurredEventArgs.

AudioSignalProblemOccurred デリゲートを作成する場合は、イベントを処理するメソッドを指定します。When you create an AudioSignalProblemOccurred delegate, you identify the method that will handle the event. イベントをイベント ハンドラーに関連付けるには、デリゲートのインスタンスをイベントに追加します。To associate the event with your event handler, add an instance of the delegate to the event. デリゲートを削除しない限り、そのイベントが発生すると常にイベント ハンドラーが呼び出されます。The event handler is called whenever the event occurs, unless you remove the delegate. イベント ハンドラー デリゲートの詳細については、次を参照してください。イベントとデリゲートします。For more information about event-handler delegates, see Events and Delegates.
