Property Value

Type: Microsoft.Speech.Recognition.RecognizedAudio
The audio associated with the recognition result or a null reference (Nothing in Visual Basic) if the recognizer generated the result from a call to the EmulateRecognize() or EmulateRecognizeAsync() methods.


The following example shows a handler for the SpeechRecognized event and some of the information about the associated RecognitionResult.

// Handle the SpeechRecognized event. 
void SpeechRecognizedHandler(object sender, SpeechRecognizedEventArgs e)
  if (e.Result == null) return;

  // Add event handler code here.

  // The following code illustrates some of the information available
  // in the recognition result.
      Console.WriteLine("Grammar({0}): {1}", e.Result.Grammar.Name, e.Result.Text);
      Console.WriteLine("Audio for result:");
      Console.WriteLine("  Start time: "+ e.Result.Audio.StartTime);
      Console.WriteLine("  Duration: " + e.Result.Audio.Duration);
      Console.WriteLine("  Format: " + e.Result.Audio.Format.EncodingFormat);

  // Display the semantic values in the recognition result.
  foreach (KeyValuePair<String, SemanticValue> child in e.Result.Semantics)
    Console.WriteLine(" {0} key: {1}",
      child.Key, child.Value.Value ?? "null");

  // Display the recognition alternates for the result.
  foreach (RecognizedPhrase phrase in e.Result.Alternates)
    Console.WriteLine(" alt({0}) {1}", phrase.Confidence, phrase.Text);
