Hello caladium, nice to se you posting.
I use naturally speaking for years now. I started with the 3.0 and now have a newer version that voc rehab purchased for me.

The big tip is to train it and speak naturaly. I trained mine several hours, more then the short tutorial, and all of the options of text. The space fanatasy, JFK speech, many options they give so it is use to your voice in more then a story telling manner. We use expressions when we read taht during dictation we not use, so the more you use it the better it gets. Even odd speeled lat name, I say it once, it will misspell and when I say correct "****" it will remember the corection.

Good luck and keep posting,
Di
