Dragon NaturallySpeaking is a speech recognition software developed by Nuance Communications.
We carry the PC Compatible Version 13.
The software has three primary areas of functionality: dictation, text-to-speech and command input.
The user is able to dictate and have speech transcribed as written text, have a document synthesized as an audio stream, or issue commands that are recognized as such by the program.
Dragon users can launch windows, select items in a menu, "press keys," save files or even swap windows by speaking a command.
