I've been using version 10 preferred for a while and it works much better then I expected. After some initial training, I was seeing 95%+ accuracy, and now it sits around 96-97% accuracy after building up my user file (read: speech pattern recognition).I have been meaning to try Dragon for some time. How fast does it work? I see several versions for sale - is the basic cheap one good enough?
Note: Make sure you find out if Dragon works well with your operating system, you only have to read the amazon reviews to see the horror stories of having to contact Dragon support.
