Examples

The following example handles the SpeechRecognitionEngine.SpeechRecognized event and outputs to the console information about the recognized audio that is associated with the recognition result.

// Handle the SpeechRecognized event. 
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.
}
