      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 +

Comentários

Para obter qual problema ocorreu, use a AudioSignalProblem propriedade do associado AudioSignalProblemOccurredEventArgs.

Ao criar um delegado para um AudioSignalProblemOccurred evento, você identifica o método que manipulará o evento. Para associar o evento ao manipulador de eventos, adicione uma instância do delegado ao evento. O manipulador de eventos é chamado sempre que o evento ocorre, a menos que você remova o representante. Para obter mais informações sobre delegados do manipulador de eventos, consulte Eventos e delegados.
