Nuance has released their new version of Dragon NaturallySpeaking 13. Nuance released the previous version of Dragon NaturallySpeaking  in October 2012. Since then, Nuance has released one major update, and that was to 12.5.
Every time that Nuance releases a new version of Dragon NaturallySpeaking, they always provide the percentage of improvement and recognition that the application offers over the previous version. But with version 13, you can visibly see a noticeable increase with the level of recognition and responsiveness of your dictation. I have personally noticed that when I use the command for ‘correct that'; I’ve seen a much faster return on correction options.
Improvements in recognition and improving the responsiveness of issuing commands and making corrections; all these equal up to greater productivity. In my daily processes, I cannot imagine not having Dragon NaturallySpeaking available to me; it would be highly debilitating.
