SpeechRecognitionEngine.InstalledRecognizers 方法

定义

返回有关当前系统中安装的所有语音识别器的信息。

public:
 static System::Collections::ObjectModel::ReadOnlyCollection<System::Speech::Recognition::RecognizerInfo ^> ^ InstalledRecognizers();
public static System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.RecognizerInfo> InstalledRecognizers();
static member InstalledRecognizers : unit -> System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.RecognizerInfo>
Public Shared Function InstalledRecognizers () As ReadOnlyCollection(Of RecognizerInfo)

返回

描述安装的识别器的 RecognizerInfo 对象的只读集合。

示例

以下示例演示演示基本语音识别的控制台应用程序的一部分。 该示例使用 方法返回的 InstalledRecognizers 集合来查找支持英语的语音识别器。

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);
    }
  }
}

注解

若要获取有关当前识别器的信息,请使用 RecognizerInfo 属性。
