C# 自动识别所有英语单词

我有一个windows窗体应用程序。我想做一个

语音识别

。问题是，我使用的

语法仅限于我的选项列表（请参阅下面的程序）。我希望我的程序能够识别所有单词

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));

你知道如何让我的程序识别所有单词吗

源代码：
声明：

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

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(); 
    }

}

节目：

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

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(); 
    }

}

这个程序的问题是无法识别所有单词，对于我的项目，我想让它识别所有单词

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));

谢谢Stackoverflowers
如果我理解正确，您的意思是，这正是您需要的：
只需在听写模式下使用SpeechRecognitionEngine，即可识别单词（参见示例）
