Great "how-to" article on developing speech apps

I just rediscovered this great article by the awesome guys at Vertigo Software on designing
and implementing Voice-only Web Application using the Speech Application SDK
.
It's based on Beta 2, so it's not quite current but it has some really useful material
in it. It's also extremely detailed - if you want some in depth knowledge about how
to put together a professional application using our SDK I'd recommend it as a place
to start.
