My purchase of Dragon Naturally Speaking was to improve productivity and save my aching wrists. My work includes writing summaries of client visits, creative writing and maintaining a website.
I have used the Speech Recognition software that comes with Vista (kind of a joke) and Windows 7 (better) but Dragon has them both beat hands-down. Dragon has an impressive ability to 'hear' what you're saying and using it for commands works pretty good too. It also self-trains and will suggest updating its database after each session when you close out of Dragon. I haven't used it extensively yet but I'm confident that if you take the time to train it properly you won't even have to watch the monitor at all, just proofread when you are finished.
I have found the "correct" command to be a bit clunky and "spell that" has given me some trouble but the words were names or unfamiliar words and I was in a hurry so just used my keyboard for that. However I must comment that Dragon does have an excellent vocabulary of words already in it's database. As for dictation, I found I was able to speak more words in a 'packet' (at a time) than the instructions indicated. Dragon flowed along and I found I didn't have to break my sentences up into such small portions for it to keep up.
The headphones that come with it are good quality.
For absolute bliss having a wireless (bluetooth) headset would be great, an ability the higher-grade Premium version apparently offers.
This software was not sold directly from Amazon.ca but through another company and there was no difficulty whatsoever. The product arrived much sooner than the estimated delivery date. They also included a slip with contact information if I was displeased in any way.
I would highly recommend this product to anyone doing creative writing or a fair amount of typing. Or has trouble typing!
