Beispiele

Im folgenden Beispiel werden Ausdrücke wie "Liste der Künstler in der Kategorie Jazz anzeigen" oder "Album gospel anzeigen" erkannt. Im Beispiel wird ein Handler für das SpeechRecognitionRejected Ereignis verwendet, um eine Benachrichtigung in der Konsole anzuzeigen, wenn die Spracheingabe nicht mit ausreichender Zuverlässigkeit mit dem Inhalt der Grammatik abgeglichen werden kann, um eine erfolgreiche Erkennung zu erzeugen.

using System.Speech.Recognition;  

namespace SampleRecognition  
{  
  class Program  
  {  
    static void Main(string[] args)  

    // Initialize a shared speech recognition engine.  
    {  
      using (SpeechRecognizer recognizer =  
         new SpeechRecognizer())  
      {  

        // Create a grammar.  
        //  Create lists of alternative choices.  
        Choices listTypes = new Choices(new string[] { "albums", "artists" });  
        Choices genres = new Choices(new string[] {   
          "blues", "classical", "gospel", "jazz", "rock" });  

        //  Create a GrammarBuilder object and assemble the grammar components.  
        GrammarBuilder mediaMenu = new GrammarBuilder("Display");  
        mediaMenu.Append("the list of", 0, 1);  
        mediaMenu.Append(listTypes);

        Console.WriteLine("  Rejected phrase: " + phrase.Text);  
        Console.WriteLine("  Confidence score: " + phrase.Confidence);  
      }  
    }  

    // Handle the LoadGrammarCompleted event.  
    static void recognizer_LoadGrammarCompleted(object sender, LoadGrammarCompletedEventArgs e)  
    {  
      Console.WriteLine("Grammar loaded: " + e.Grammar.Name);  
    }  

    // Handle the SpeechRecognized event.  
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)

Hinweise

Das SpeechRecognitionRejected Ereignis wird von den SpeechRecognizer Klassen und SpeechRecognitionEngine ausgelöst.

SpeechRecognitionRejected-Ereignisse werden von einer Spracherkennungs-Engine generiert, wenn keines der Alternativen aus einem Erkennungsvorgang eine hohe Zuverlässigkeitsbewertung aufweist, um akzeptiert zu werden. Ausführliche Informationen zu abgelehnten Ausdrücken sind über die Result -Eigenschaft verfügbar.

SpeechRecognitionRejectedEventArgs leitet sich von ab RecognitionEventArgs.
