ABSTRACT:
A voice warning system for an automotive vehicle such that warning information is first indicated to the driver in voice form when car-radio sound volume is reduced, and next in alarm sound form, without reducing the car-radio sound volume, until the driver takes a proper action. The system thus improved comprises a discriminator having a memory, a coincidence counter, a gate, AND circuits, and OR circuits, and an alarm generator, in addition to sensors and a voice output unit.
