Abstract
A voice actuated control system for a motor vehicle. A microphone mounted to the vehicle senses user commands as well as other noise in the passenger compartment. Analog electrical signals from the microphone are converted into digital form and compared by a high speed microprocessor with a user profile. A correspondence between the profile and the sensed input causes a control function such as raising or lowering a window to be performed. A speech synthesizer in the system prompts the user in the event a command in a command sequence is inappropriate.
