private void recognizerInfoButton_Click(object sender, EventArgs e) 
{
  RecognizerInfo info = _recognizer.RecognizerInfo;
  string AudioFormats = "";
  foreach (SpeechAudioFormatInfo fmt in info.SupportedAudioFormats) 
  {
    AudioFormats += String.Format("       {0}\n", fmt.EncodingFormat.ToString());
  }
  string AdditionalInfo = "";
  foreach (string key in info.AdditionalInfo.Keys) 
  {
    AdditionalInfo += String.Format("      {0}: {1}\n", key, info.AdditionalInfo[key]);
  }
  MessageBox.Show(String.Format(
                     "Name:                 {0 } \n" +
                     "Description:          {1} \n" +
                     "SupportedAudioFormats:\n" +
                     " {2} " +

                     "AdditionalInfo:       \n" +
                     " {4}\n",
                     info.Name.ToString(),
                     info.Description.ToString(),
