Examples

The following example implements a button click that displays all the information in a RecognizerInfo instance. The example uses the SupportedAudioFormats property to obtain the encoding formats supported by a recognition engine configuration, and then displays it in a MessageBox.

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} " +  
                           "Culture:              {3} \n" +  
                           "AdditionalInfo:       \n" +  
                           " {4}\n",  
                           info.Name.ToString(),  
                           info.Description.ToString(),  
                           AudioFormats,  
                           info.Culture.ToString(),  
                           AdditionalInfo));  
}
