Ejemplos

En el ejemplo siguiente se define un controlador de eventos que recopila información sobre un AudioSignalProblemOccurred evento.

private SpeechRecognizer recognizer;  

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

  // 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.  
}  

Comentarios

Para obtener el problema que se produjo, use la AudioSignalProblem propiedad del asociado AudioSignalProblemOccurredEventArgs.

Al crear un delegado para un AudioSignalProblemOccurred evento, se identifica el método que controlará el evento. Para asociar el evento al controlador, se debe agregar una instancia del delegado al evento. Siempre que se produce el evento, se llama a su controlador, a menos que se quite el delegado. Para obtener más información sobre los delegados del controlador de eventos, vea Eventos y delegados.
