here is code:

C#

{
      SpeechRecognizer recognizer = new SpeechRecognizer();
      recognizer.Enabled = true;

      Choices folderPath= new Choices();
      folderPath.Add(new string[] { "My Computer", "My Documents", "my docs", "Sumeet", "gehi"});

      GrammarBuilder gb = new GrammarBuilder(folderPath);

      Grammar gramer = new Grammar(gb);
      recognizer.LoadGrammar(gramer);

      gramerSpeechRecognized+=new EventHandler<SpeechRecognizedEventArgs (gramer_SpeechRecognized);
  }
  void gramer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
  {

      if (e.Result.Text == "computer" || e.Result.Text=="my computer")
      {
         string myComputerPath = Environment.GetFolderPath(Environment.SpecialFolder.MyComputer);
      System.Diagnostics.Process.Start("explorer", myComputerPath);
    //OR
      //System.Diagnostics.Process.Start("explorer", "::{20d04fe0-3aea-1069-a2d8-08002b30309d}");
      }

Yes, it doesn't compare

What exactly does "doesn't compare" mean? Does your event handler run? What are you getting in e.Result?

the work of this code is when i say something through mic it will display in text-box & when i say computer or my computer it will open my computer, when i say my computer textbox display that i have said but cant open my computer folder, it did not compare with e.result.text

Good to hear that,i attended this year imagine cup with this project,:). Btw,this is not the way to do the task.Where is your grammer? Without GrammerBuilder how could you recognize voice!?

Hi,

Probably, "My Computer" is capitalized, so the input is "My Computer", which is NOT equal to "my computer"!
Try this:

C#

void gramer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        string resultText = e.Result.Text.ToLower();
        if (resultText == "computer" || resultText =="my computer")
        {

Hope this helps.
