语音识别所有英语单词自动

我有一个windows窗体应用程序。我想做一个Voice Recognition。问题是我使用的Grammar在我的选择列表中受到限制(参见下面的程序)。我希望我的程序能够识别所有的单词。

Choices sList = new Choices();
sList.Add(new string[] { "hello", "test", "it works", "how", "are", "you", "today", "i", "am", "fine", "exit", "close", "quit", "so" });
    Grammar gr = new Grammar(new GrammarBuilder(sList));

你知道我怎样才能使我的程序识别所有的单词吗?

源代码:

声明:

using System.Speech;
using System.Speech.Recognition;
using System.Speech.Synthesis;

计划:

private void button2_Click(object sender, EventArgs e)
{
    button2.Enabled = false; // Start record
    button3.Enabled = true;  // Stop record
    Choices sList = new Choices();
    sList.Add(new string[] { "hello", "test", "it works", "how", "are", "you", "today", "i", "am", "fine", "exit", "close", "quit", "so" });
    Grammar gr = new Grammar(new GrammarBuilder(sList));
    try
    {
        sRecognize.RequestRecognizerUpdate();
        sRecognize.LoadGrammar(gr);
        sRecognize.SpeechRecognized += sRecognize_SpeechRecognized ;
        sRecognize.SetInputToDefaultAudioDevice();
        sRecognize.RecognizeAsync(RecognizeMode.Multiple);
        sRecognize.Recognize();
    }
    catch
    {
        return;
    }
 }
private void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    if (e.Result.Text == "exit")
    {
        Application.Exit();
    }
    else
    {
        textBox1.Text = textBox1.Text + " " + e.Result.Text.ToString(); 
    }
}

这个程序的问题是不能识别所有的单词，对于我的项目，我想让它识别所有的单词。
