Ejemplos

En el ejemplo siguiente se reconocen frases como "Mostrar la lista de artistas en la categoría de jazz" o "Mostrar álbumes gospel". En el ejemplo se usa un controlador para el SpeechRecognitionRejected evento para mostrar una notificación en la consola cuando la entrada de voz no puede coincidir con el contenido de la gramática con suficiente confianza para generar un reconocimiento correcto.

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);  
    }  
  }  
}  

Comentarios

El SpeechRecognitionRejected evento lo generan las SpeechRecognizer clases y SpeechRecognitionEngine .

Los eventos SpeechRecognitionRejected se generan mediante un motor de reconocimiento de voz cuando ninguna de las alternativas de una operación de reconocimiento tiene una puntuación de confianza lo suficientemente alta como para aceptarse. La información detallada sobre las frases rechazadas está disponible a través de la Result propiedad .

SpeechRecognitionRejectedEventArgs deriva de RecognitionEventArgs.
