Please have a look at the following code
private void button2_Click(object sender, EventArgs e)
{
SpeechRecognizer sr = new SpeechRecognizer();
Choices colors = new Choices();
colors.Add(new string[] { "red arrow", "green", "blue" });
GrammarBuilder gb = new GrammarBuilder();
gb.Append(colors);
Grammar g = new Grammar(gb);
sr.LoadGrammar(g);
// SpeechSynthesizer s = new SpeechSynthesizer();
// s.SpeakAsync("start speaking");
sr.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sr_SpeechRecognized);
}
void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
MessageBox.Show(e.Result.Text);
}
This is normal speech recognition code which uses the MS speech engine. You can see here that I have loaded some grammar. But, there is an issue as well. That is, this is not responding only to the given grammar but also to the MS Built-In speech commands! Like speech command to minimize a window, open start menu etc!
I really don't need that. My application should only respond to my grammar and not to MS built-in commands. Is there is a way I can achieve this?

The SpeechRecognizer
object builds on top of the existing Windows Speech system. From MSDN:
Applications use the shared recognizer to access Windows Speech Recognition. Use the SpeechRecognizer object to add to the Windows speech user experience.
Consider using a SpeechRecognitionEngine object instead as this runs in-process rather than system-wide.
