Overview

Mac OSX has a suite of programs that allow the user to interact with his or her computer without the aid of a mouse or keyboard. Unfortunately, the Mac OSX voice control, dictation and voice does not train the computer to recognize one’s voice and may have limited functionality for controlling the computer. Therefore, for Mac users if they are going to doing a lot of dictation and or voice control, please consult the ITS support center.
