Abstract
A spoken-instruction controlled system for an automotive vehicle by which a single actuator can be activated repeatedly or a plurality of actuators can be activated sequentially by repeatedly depressing a recognition switch within a predetermined time period after a spoken instruction corresponding to the single actuator or actuators has been recognized by a speech recognizer. Therefore, it is possible to activate an actuator repeatedly or actuators sequentially without uttering the same spoken instruction repeatedly. The spoken-instruction controlled system according to the present invention comprises a two-circuit analog switch, at least one analog switch, at least one retriggerable timer unit, an AND gate, an OR gate, a shift register, etc., in addition to a speech recognizer.
