2. A speech recognition system for an automotive vehicle for sequentially actuating a device having a plurality of different operation modes by sequentially energizing a plurality of actuators in accordance with a plurality of spoken instructions uttered into a microphone, which comprises: (a) a recognition switch (3) for deriving a recognizing signal when closed; (b) a reset switch (103) for deriving a reset signal when closed; (c) an analysis section (101) for analyzing spoken instruction signals supplied thereto by the microphone while said recognition switch is closed; (d) a memory unit (10) for storing spoken instruction signals analyzed by said analysis section; (e) a comparison section (102) for comparing the spoken instruction signals stored in said memory unit with previously stored reference spoken instruction signals and for activating one of the actuators separately when both the signals match; (f) a reference pattern memory unit (11) including: (1) at least one device instruction phrase memory unit (11-1) for storing reference spoken instruction signals corresponding to at least one device; and (2) a plurality of operation-mode instruction phrase memory units (11-2) for storing reference spoken instruction signals corresponding to a plurality of operation-modes for the at least one device; (g) a reference pattern memory selector (105) for switching connections which normally subsist between said comparison section and said device instruction phrase memory unit to establish connections between said comparison section and one of said operation-mode instruction phrase memory units; and (h) a controller connected to said recognition switch, said reset switch, said analysis section, said memory unit, said comparison section, said reference pattern memory unit, and said reference pattern memory selector, said controller supplying various command signals to the entire system in such a way that: (1) said reference pattern memory selector connects said comparison section to said at least one device instruction phrase memory unit for recognizing at least one device instruction phrase in response to the recognizing signal; (2) after the device instruction phrase has been recognized, said reference pattern memory selector automatically connects said comparison section to one of said operation-mode instruction phrase memory units corresponding to the recognized device for recognizing one of the operation-mode instruction phrases to actuate one of the actuators corresponding thereto; (3) the recognized spoken instruction phrase is cancelled in response to the resetting signal; and (4) the actuated actuator is stopped and said reference pattern memory selector connects said comparison section to the succeeding one of said operation-mode instruction phrase memory units corresponding to the recognized device for recognizing the succeeding one of operation-mode instruction phrases to actuate one of the actuators corresponding thereto in response to the resetting signal, whereby after a device instruction phrase has once been supplied to the system, it is possible to sequentially actuate a plurality of actuators corresponding to a device by closing said reset switch repeatedly and deriving only the operation-mode instruction phrase sequentially without uttering the same device spoken instruction repeatedly.
