Is it possible to replace the sList i created to something with a bigger vocab?

C#

private void button2_Click(object sender, EventArgs e)
        {
            button2.Enabled = false;
            button3.Enabled = true;
            Choices sList = new Choices();
            sList.Add(new string[] { "hello", "test", "it works", "how", "are", "you", "today", "i", "am", "fine", "exit", "close" });
            Grammar gr = new Grammar(new GrammarBuilder(sList));
            try
            {
                sRecognize.RequestRecognizerUpdate();
                sRecognize.LoadGrammar(gr);
                sRecognize.SpeechRecognized +=sRecognize_SpeechRecognized;
                sRecognize.SetInputToDefaultAudioDevice();
                sRecognize.RecognizeAsync(RecognizeMode.Multiple);
           
            }

Thank you for any help.

Why? The existing engine already uses some dictionary. Yes, you can just create a bigger grammar, but the quality of recognition then (sigh...)...

I shouldve been clearer. i meant an external dictionary(like a website or a stored file), how would i call it? so when i say words other than "hello", "test", "it works", "how", "are", "you", "today", "i", "am", "fine", "exit", "close" it will recognize it.

Why? The words you've listed are already in the general dictionary. What's your purpose?

I want to be able to speak an essay and for the program to pick it up and display it as text. at the moment it only picks up the words ive listed as a demo. i was wondering if there was a way to get every single word without listing each seperate word in the english language.

With such spelling as yours, it's hard to hope for something good. :-)
And I'm not quite joking: everyone can use spell checker when asking question. I think this is a matter of pure politeness.

Now, you can use System.Speech.Recognition.DictationGrammar:

However, don't hold your breath — it can make the quality of recognition prohibitively poor. No wonder, so many words are so similar in pronunciation. I tried some better engines (on Android, for example), but all free-of-charge engines I tried on Windows so far was too bad to take seriously. Just give it a try though.
