Dragon NaturallySpeaking is a speech recognition software developed by Nuance Communications. It supports 32 and 64-bit versions of Windows XP, Vista and 7. There is also a Mac OS version called Dragon Dictate. The software can be used for dictation, text-to-speech or command input.
Dragon is a really interesting interface, because it allows a user to interact with a computer without making contact with a mouse or keyboard. You talk and it types. It allows you to write documents, emails and even issue commands in a more natural way. Check out the video below.
