The system time at the start of the recognition operation.

Examples

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

C#

// 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.  
}  

Remarks

The StartTime property gets the system time at the start of the recognition operation, which can be useful for latency and performance calculations.

The AudioPosition property gets the location in the input device's generated audio stream.
