I am looking for some

Answer 1

The classes in System.Speech are for text to speech (primarily an acessibility feature).

You are looking for voice recognition. There is the System.Speech.Recognition namespace available since .Net 3.0. It uses the Windows Desktop Speech engine. This might get you started, but I guess there are better engines out there.

Voice recognition is very complicated and hard to do right, there are also some commercial products available.
