Hi Carolyn,
I used Dragon dictate for quite a while 2 years back.
You need a lot of patience, but it is worth it when you finally get it "trained". It only works with your voice and if it misspells a word, you have to train it to recognise that word.
A funny story about it is I was showing it to my son and his wife,
and was dictating and it was working fine. However, something distrascted them and they started talking. Any noise it does not recognise causes it to type rubbish. I said to it, "You stupid computer", and it simply replired,
"Whatever"!!!!
I always said it had a mind of its own.
Cheers
Ron
