SpeechRecognizer.SpeechRecognized事件不适用于语音识别器（英语-英国）

Question

我用C＃创建了一个简单的语法，然后使用了SpeechRecognizer.SpeechRecognized Event。 但是我不知道为什么它可以与Microsoft Speech Recognizer（英语-美国）一起使用，但是不能与Microsoft Speech Recognizer（英语-英国）一起使用。

这是代码：

    private void button1_Click(object sender, EventArgs e)
    {
        System.Speech.Recognition.SpeechRecognizer sr = new SpeechRecognizer();
        Choices Slist = new Choices();
        Slist.Add(new string[] { "Brazil", "Germany", "Argentina", "Netherlands" });
        Grammar gr = new Grammar(new GrammarBuilder(Slist));
        sr.RequestRecognizerUpdate();
        sr.LoadGrammarAsync(gr);
        sr.SpeechRecognized += sr_SpeechRecognized;

    }

    void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        if (e.Result.Text.ToString()== "Brazil")
        {
            MessageBox.Show("Fourth");
        }
        if (e.Result.Text.ToString() == "Germany")
        {
            MessageBox.Show("First");
        }
        if (e.Result.Text.ToString() == "Argentina")
        {
            MessageBox.Show("Second");
        }
        if (e.Result.Text.ToString() == "Netherlands")
        {
            MessageBox.Show("third");
        }
    }

任何帮助，将不胜感激。

显然， GrammarBuilder对象上的Culture属性必须与识别器的Culture相匹配才能使识别GrammarBuilder 。
