I've been going through my CD's for Hal related files, noticed I started out with version 3, I'm now at 10.1 needed for win 7 64 bit, I've gotten used to dragon and the dragon commands. I'd say Dragon started getting pretty good at version 7 and has improved a bit since then. As far as I know you will need need v 10.1 or higher to have it work with win 7 64 bit.
All the mics I've used were tested in the dragon mic setup which gives the s/n ratio. The majority of the mics sold will give you a s/n ratio of 18 to 21 the same as you'd get from a radio shack $3 mic.
Anyways with dragon dictate into some notepad or dragonpad and save the files and let dragon read them, this works great to improve the relationship of which words are used together. I also have a txt with a list of stores, friends names, street names ect, after reading the list it gets them right the frist time.
