void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)  
{  
  if (e.Result == null) return;  

  RecognitionResult result = e.Result;  

  Console.WriteLine("Grammar({0}): {1}",  
    result.Grammar.Name, result.Text);  

  if (e.Result.Audio != null)  
  {  
    RecognizedAudio audio = e.Result.Audio;  

    Console.WriteLine("   start time: {0}", audio.StartTime);  
    Console.WriteLine("   encoding format: {0}", audio.Format.EncodingFormat);  
    Console.WriteLine("   position: {0}, duration: {1}",  
      audio.AudioPosition, audio.Duration);  
  }  

  // Add event handler code here.
