I have Dragon Naturally speaking v 7.2 Pro. (about $450-550)
Suggest you try that or Dragon Naturally Speaking Preferred.
(149 - 199).
Good prices on either at www.knowbrainer.com
Recognition accuracy is very good with either (same engine). Difference w/ Pro is better mike, macro editor, support for Outlook vs just Outlook express.
I believe that Dragon and Via Voice (IBM) have similar accuracy, but Dragon has an easier to use interface.
VR likes a pretty fast machine (at least PIII 500) and ample memory. Also, sound quality is important. For some notebooks and desktops, you get better recognition with a USB mike rather than using the sound card or built in sound.
One big improvement starting several versions ago with Dragon was speedy training. You can get pretty good accuracy after about 15 minutes. You also can/should scan some of your writing to allow the product to learn your vocabulary and style. After that you train out the mistakes.
I’d be dictating this but the kids are asleep in the next room.
If you are in the medical profession, get the Medical version.
Best to spend the extra money to buy that or Pro from a VAR.
If Boston, I recommend Peter Cohen Associates. He sells specialized vocabularies on top of Dragon Medical and templates etc.
