From Jonathan Garcia, a program manager in Windows:

Please send us feedback on Vista speech recognition!

A lot of you have already posted or sent us a lot of valuable
feedback. We have collected it already in majority but you can still
re-send it or point us to it again. We want to make sure that
everybody has had the opportunity to give feedback.

What we like to know is:
1. Are you a dictation user (still use keyboard/mouse with SR) or
hand-free user (rarely use keyboard/mouse)?
2. Do you use Vista speech as your primary SR tool or do you use
another one (please name it)?
2. What do like in Vista SR?
3. What is missing/broken/not good in Vista SR?

Please stack rank the feature requests/problems from 1 to N

You can email all the feedback here: listen@microsoft.com
**Deadline is Monday April 30 2007**
