I am writing this review using version 9 of Dragon NaturallySpeaking (Standard Edition). I have only been using it for a very short time, but already I can tell that it has adapted to my own voice, and the accuracy is excellent!
Over the years, I have experimented with a variety of voice recognition programs, and I have to say that Dragon NaturallySpeaking wins hands down. You can speak naturally and clearly, and the program will recognize everything that you are saying. What's more, the Voice Commands built into the program are mostly very intuitive; a lot of thought has obviously gone into how to lay out the various options for making corrections and editing text.
