do you use speech recognition in vista  

No, I don't use it.
If it was just me I might.
But there are three of us that use the computer and only one of us would be able to use it, I think.
I will have to look at it some more.
We all have our own desktop so maybe it could recognize each one of us.
Would feel all Star Trekky.
I might just have to go read up on it.

yes i use it and it is a very interesting feature and it has helped me a lot and i also used it in xp

I tried it, it's fun but I don't find it so usable. It keeps misunderstanding me :D
But I do have use of it when reading e-books.
