If I may give a good suggestion, don't use microsofts speech sdk. It sucks. If you download it (142 mb !!!!!!) It sure looks good, but the only samples are created in C++ and if you vind a way to download a couple of ocx's who can work with the sdk. These ocx's are so very slow !!! Really don't use microsoft speech sdk. I'm looking for an other one myself. But haven't found it yet.
