So far, I rate it as a 4 star, as NaturallySpeaking does what it claims to do, but we are not yet fluent users, and still have to make a lot of manual corrections.
This software was purchased for the purposes of helping my two sons (who each have learning disabilities and ADHD) with homework assignments (and becasue it is a tool currently used by our public school system).
We are still in training mode with the program, and it is having some trouble with speech patterns and word recognition. We are also struggling with the correct commands it requires for executing tasks (like spelling corrections, text selections and deletions). So far, it has been interesting learning how to use it, and we are persevering through the bumps with speech recognition. It is my understanding that the more a user reads and dictates, the more accurate Dragon NaturallySpeaking is supposed to get.
If this software can help my boys get their thoughts, opinions and answers on paper, and help them find more academic success, it will be well worth the time and effort put in to train it to interpret their speech patterns (Because I am growing TIRED of acting as their Scribe!).
