SAPI4 Question

How do I set the default voice for SAPI4? Unlike SAPI5 where you can
even do a test sentence there does not appear to be a way to select
the voice! I am using AT&T voices but I cannot select them in my
software or on the control panel. I have a Microsoft agent2
application using VB .net on XP.

I know the voces work since I can test them individually doing the
pronounciation thing though it appears to default to a voice I don't
want.Failing that can I do an enum thing in VB .net for SAPI4?


Thanks
