Speech Recognition in Windows XP

I used the Microsoft Windows Speech SDK 5.1 to make some applications. What I did not find and could not figure out is how to change to a different profile through code in VB 6. I currently have to two profile trained (one with my voice and one with my brother's voice) and I would to create a button(s) that select different trained speech profiles in the vb app. Does anyone know how to do this?

Thank you in advance.

I'm looking for the same answer.

I'm also trying to figure out how to create customized training sessions. The ones provided are too difficult for the kids I' trying to code for.
