Exempel

I följande exempel visas användningen av en händelsehanterare för Grammar objektets SpeechRecognized händelse. Den matar ut igenkänningsresultatet till konsolen.

public partial class Form1 : Form
{
  SpeechRecognitionEngine sre;

  public Form1()
  {
  InitializeComponent();

  // Create an in-process speech recognizer.
  sre = new SpeechRecognitionEngine();

  // Configure input to the speech recognizer.
  sre.SetInputToDefaultAudioDevice();

  // Create a simple grammar and load it.
  Grammar testGrammar = new Grammar(new GrammarBuilder("testing"));
  sre.LoadGrammarAsync(testGrammar);

  // Add a handler for the grammar's speech recognized event.
  testGrammar.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(testGrammar_SpeechRecognized);

  // Start asynchronous speech recognition.
  sre.RecognizeAsync();
  }

  // Handle the grammar's SpeechRecognized event, output the recognized text.
  void testGrammar_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
  {
    Console.WriteLine("Recognized text: " + e.Result.Text);
  }
}

Kommentarer

Taligenkänningen genererar också en SpeechRecognized händelse när den känner igen indata. Objektets GrammarSpeechRecognized händelse utlöses före taligenkänningens SpeechRecognized händelse . Mer information finns i SpeechRecognizer.SpeechRecognizedhändelserna , SpeechRecognitionEngine.SpeechRecognizedoch RecognizeCompleted .

Alla uppgifter som är specifika för en viss grammatik bör alltid hanteras av hanterare för Grammar objektets SpeechRecognized händelse.
