Dragon software

Dragon Naturally Speaking is a good software for controlling your computer through voice.  You can do commands through it but what I like is if I am typing alot I can just talk and it will type it for your.  There is a little adjustment curve and you know how I talk so it has to adjust to your voice.   The longer you use it the more accurate it is becuase as you correct things it "remembers" and will adjust next time.  It is a little pricey...$100 -200 depending on what you get but it can be very beneficial.
