// Handle the SpeechRecognized event. 
void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)
{
  if (e.Result == null) return;

  // Add event handler code here.

  // The following code illustrates some of the information available
  // in the recognition result.
      Console.WriteLine("Grammar({0}): {1}", e.Result.Grammar.Name, e.Result.Text);
      Console.WriteLine("Audio for result:");
      Console.WriteLine("  Start time: "+ e.Result.Audio.StartTime);
