It is entirely dependant on what speech recognition library you are using – Chris Laplante Jan 23 '14 at 16:30

Lexicons aren't exposed via System.Speech.Recognition, unfortunately. You can access lexicons using the SpeechLib automation interface to SAPI, though; the object you want to create is SpLexicon.
Note that System.Speech.Recognition will automatically load any user lexicons, so you can have a separate app to build the lexicon and your reco app can continue to use System.Speech.Recognition.
Also, if you're using a command & control grammar, you should specify pronunciations directly; for example, the SrgsToken class allows you to explicitly specify a pronunciation for the word. (Unfortunately, I can't remember how to do this with System.Speech.Recognition.GrammarBuilder, but it is possible.)

@prafullagrawal Look at [this answer](http://stackoverflow.com/questions/19994663/how-to-open-sapi-train-window-in-a-c-sharp-application/20028368#20028368) to see how to integrate SpeechLib, and then just call `new SpLexicon` to create the object and then call `AddPronunciation` to add the pronunciation. Since you will likely need custom pronunciations, the [English phone set documentation](http://msdn.microsoft.com/en-us/library/ee431828(v=vs.85).aspx) will also be handy. – Eric Brown Jan 24 '14 at 18:08
