Devoluções

Uma coleção de apenas leitura dos RecognizerInfo objetos que descrevem os reconhecedores instalados.

Exemplos

O exemplo seguinte mostra parte de uma aplicação de consola que demonstra reconhecimento básico de voz. O exemplo utiliza a coleção devolvida pelo InstalledRecognizers método para encontrar um reconhecedor de fala que suporta a língua inglesa.

using System;
using System.Speech.Recognition;

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

      // Select a speech recognizer that supports English.
      RecognizerInfo info = null;
      foreach (RecognizerInfo ri in SpeechRecognitionEngine.InstalledRecognizers())
      {
        if (ri.Culture.TwoLetterISOLanguageName.Equals("en"))
        {
          info = ri;
          break;
        }
      }
      if (info == null) return;

      // Create the selected recognizer.
      using (SpeechRecognitionEngine recognizer =
        new SpeechRecognitionEngine(info))
      {

        // Create and load a dictation grammar.
        recognizer.LoadGrammar(new DictationGrammar());

        // Add a handler for the speech recognized event.
        recognizer.SpeechRecognized +=
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);

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

        // Start asynchronous, continuous speech recognition.
        recognizer.RecognizeAsync(RecognizeMode.Multiple);

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

    // Handle the SpeechRecognized event.
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
      Console.WriteLine("Recognized text: " + e.Result.Text);
    }
  }
}
