MSDN webcast on professional speech development
There are a number of resources available at http://www.microsoft.com/speech to people who want to learn about speech application development, but if you'd prefer to participate in a webcast, MSDN is sponsoring this one:
Quick and Easy Professional Speech Applications On MS Speech Server Using High Level Metaphor Resources - Level 200
I don't know much about it, but if you're interested in speech development, it's worth looking through resources like this and others on the MSDN site.
