Abstract
A voice actuated control system for controlling vehicle accessories includes a voice processing circuit and memory for storing data representing command words employed to perform control functions for vehicle accessories and for detecting spoken command words and providing data corresponding thereto. A microprocessor compares the data to determine if a word match has occurred and provides a selected control output signal in such event. The microprocessor is coupled by an interface circuit to a plurality of devices to be controlled including for example, a cellular telephone, a radio receiver and the like. Also, in a preferred embodiment a display and control panel is provided to selectively provide visual prompts to the operator and a manual control. The microprocessor is programmed to provide a variety of tests on stored data and spoken word to improve the reliability of the system.
