语音自动识别所有英语单词

Question

I have a windows form application. I want to make a Voice Recognition . The problem is the Grammar i used is limited from my choices list (see the program below). I want to my program be able to recognise all words.

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));

Do you know how can i make my program recognise all words ?

Source code :

Declaration :

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

Program :

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(); 
    }

}

The problem with this program don't recognise all words, and for my project i want to make it recognise all words.

Thanks Stackoverflowers

如果我理解正确，你的意思是，这应该是你需要的：只需在DictationMode中使用SpeechRecognitionEngine，就像识别单词一样（参见例如http://csharp-tricks-en.blogspot.de/2011/03 /speech-recognition-part-1-dictation-mode.html ）
