I too am using NaturallySpeaking. In the title of this post I said hi Mark! Look what it wrote.
Now, you simply have to talk to us, because it will keep our minds sharp, trying to figure out what you are saying.
Actually it was easy. I understood what you were saying. It took a couple days of training before mine worked well.
I did a lot of word training.
So hang in there and will keep up with you.
Hope
