Exempel

I följande exempel visas en hanterare för händelsen SpeechRecognized och en del av informationen om den associerade 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");
  }
  Console.WriteLine();

  // Display information about the words in the recognition result.
  foreach (RecognizedWordUnit word in e.Result.Words)
  {
    RecognizedAudio audio = e.Result.GetAudioForWordRange(word, word);
    Console.WriteLine(" {0,-10} {1,-10} {2,-10} {3} ({4})",
      word.Text, word.LexicalForm, word.Pronunciation,
      audio.Duration, word.DisplayAttributes);
  }

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