any errors?

Pheonyx 13-Mar-13 8:59am

Are you getting an error?
Firstly, I would change the order of code in your constructor to be:

InitializeComponent();
SpeechRecognitionEngine sp = new SpeechRecognitionEngine();

instead of what you have.

What does "it does not work properly" even mean?

What is not running? All I see on first look is, that you have a SpeechRecognitionEngine sp in the ctor and you're not using it.

Where do you call the LoadDictationGrammars method?

I have no idea what is wrong with your code, but luckily I have made a similar program an hour ago. This code will work, maybe you should add some adjustments though:

C#

SpeechRecognitionEngine Engine = new SpeechRecognitionEngine();
DictationGrammar Grammar = new DictationGrammar();

private void frmManager_Load(object sender, EventArgs e)
{
    /* Set to the default device. */
    Engine.SetInputToDefaultAudioDevice();

    /* Enable Dictation Grammar. */
    Grammar.Name = "Default Dictation";
    Grammar.Enabled = true;

    /* Add the Grammar. */
    Engine.LoadGrammar(Grammar);

    /* Handle Events. */
    Engine.SpeechRecognized += new EventHandler<speechrecognizedeventargs>(Engine_SpeechRecognized);

    /* Do speak. */
    Engine.RecognizeAsync(RecognizeMode.Multiple);

}

void Engine_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    string RecognizedText = e.Result.Text;

    /*richTextBox.Text = RecognizedText ?*/

}
