Exemples

L’exemple suivant reconnaît des expressions telles que « Afficher la liste des artistes de la catégorie jazz » ou « Afficher des albums gospel ». L’exemple utilise un gestionnaire pour l’événement SpeechRecognitionRejected pour afficher une notification dans la console lorsque l’entrée vocale ne peut pas être mise en correspondance avec le contenu de la grammaire avec suffisamment de confiance pour produire une reconnaissance réussie.

using System;  
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);  
        mediaMenu.Append("in the", 0, 1);  
        mediaMenu.Append(genres);  
        mediaMenu.Append("category", 0, 1);  

        //  Build a Grammar object from the GrammarBuilder.  
        Grammar mediaMenuGrammar = new Grammar(mediaMenu);  
        mediaMenuGrammar.Name = "Media Chooser";  

        // Attach event handlers.  
        recognizer.LoadGrammarCompleted +=  
          new EventHandler<LoadGrammarCompletedEventArgs>(recognizer_LoadGrammarCompleted);  
        recognizer.SpeechRecognized +=  
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);  
        recognizer.SpeechRecognitionRejected +=   
          new EventHandler<SpeechRecognitionRejectedEventArgs>(recognizer_SpeechRecognitionRejected);  

        // Load the grammar object to the recognizer.  
        recognizer.LoadGrammarAsync(mediaMenuGrammar);  

        // Keep the console window open.  
        Console.ReadLine();  
      }  
    }  

    // Handle the SpeechRecognitionRejected event.  
    static void recognizer_SpeechRecognitionRejected(object sender, SpeechRecognitionRejectedEventArgs e)  
    {  
      Console.WriteLine("Speech input was rejected.");  
      foreach (RecognizedPhrase phrase in e.Result.Alternates)  
      {  
        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)  
    {  
      Console.WriteLine("Speech recognized: " + e.Result.Text);  
    }  
  }  
}  

Remarques

L’événement SpeechRecognitionRejected est déclenché par les SpeechRecognizer classes et SpeechRecognitionEngine .

Les événements SpeechRecognitionRe éjectés sont générés par un moteur de reconnaissance vocale quand aucun des remplaçants d’une opération de reconnaissance n’a un score de confiance suffisamment élevé pour être accepté. Des informations détaillées sur les expressions rejetées sont disponibles via la Result propriété .

SpeechRecognitionRe éjectéEventArgs dérive de RecognitionEventArgs.
