A barrier operator system, such as a garage door operator system, includes one or more remote control units, such as an inside remote control unit, an external wall mounted remote control unit and portable vehicle disposed remote control units which include speech recognition modules for recognizing spoken command signals to open or close a garage door or energize or de-energize lighting associated with the garage. The speech recognition modules are operably connected to interface or microcontroller circuits for operating a radio frequency transmitter for sending signals to operate lighting, and/or the barrier operator to move a barrier between open and closed positions, and possibly perform other functions.
