Contoh

Contoh berikut menunjukkan bagian dari aplikasi konsol yang menunjukkan pengenalan ucapan dasar. Contoh menggunakan koleksi yang dikembalikan oleh InstalledRecognizers metode untuk menemukan pengenal ucapan yang mendukung bahasa Inggris.

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);
    }
  }
