我试图启动一个简单的语音识别程序，但是它不起作用，我已经安装了某些语言（en-GB和en-US），但是每当我使用以下语言时：

SpeechRecognitionEngine.InstalledRecognizers

它返回一个空集合。即使我只是尝试启动识别器，它也会返回“ 未安装识别器 ”。但是当我重新安装一种语言时，它说它已经被安装了。

using ( SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US")))
{
    // 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();
    }
}

由于什么原因无法找到已安装的识别器？

编辑：

例外是：{System.ArgumentException：找不到所需ID的识别器。参数名称：System.Speech.Recognition.SpeechRecognitionEngine..ctor的区域性（CultureInfo文化）

和：var recognizers = SpeechRecognitionEngine.InstalledRecognizers();返回计数为0的集合

我遇到了一些奇怪的东西,我创建了一个带有反射的类的实例,它传递了几个参数,一个是变量:ipAddress,当在构造函数中创建实例时,变量存储在一个字段中,但是一旦构造函数完成后,我(在调试器中)返回到我创建实例的行,我在类中检查并且字段'ipAddress'已更改为null.这怎么可能？

这是课程的一部分:

    private BPUConsole bpuConsole { get; set; }

    TcpIpServer server;
    string ipAddress;

    public moxa_nport_5110(Delegate TriggerCallBackMethod, Delegate Callback, params object[] CtorParam)
    {
        #region Initialize
        triggerCallBackMethod = TriggerCallBackMethod;
        instanceName = (string)CtorParam[0];
        string ipAddress = (string)CtorParam[1];
        int Port = (int)CtorParam[2];
        bpuConsole = new BPUConsole(Callback, instanceName);
        #endregion

        server.OnAbnormalConnectionDisconnect += new TcpIpServer.InfoEventHandler(server_OnAbnormalConnectionDisconnect);
        server.AddClient(ipAddress, 1);
    }
