1. A voice response control system for use in an automotive vehicle, comprising:
- (a) A voice recognition unit for recognizing a voice instruction given thereto and operating at least one component installed on said automotive vehicle in accordance with the given voice instruction, said voice recognition unit generating a completion signal at the termination of recognition of the given voice instruction; and
(b) a control unit for controlling at least one sounding device generating a sound during its operation, said control unit including;
a start signal generator having a start switch for generating a start signal when said start switch is turned on; and
control means, responsive to the start signal from said start pulse generator, for reducing the level of the sound from said sounding device to a predetermined value sufficient to ensure correct voice instruction recognition of said voice recognition unit, said control means generating a control signal to said voice recognition unit to thereby place the same in a condition waiting for a voice instruction after the level of the sound from said sounding device falls to the predetermined value, said control means, responsive to the completion signal from said voice recognition unit, for causing said sounding device to return to its initial sound level.

14. A voice response control system for use in an automotive vehicle, comprising:
-
(a) a voice recognition unit for recognizing a voice instruction given thereto and operating at least one component installed on said automotive vehicle in accordance with the given voice instruction, said voice recognition unit generating a completion signal at the termination of recognition of the given voice instruction; (b) a control unit for controlling at least one of side and roof windows, said control unit including; a start signal generator having a start switch for generating a start signal when said start switch is turned on; and a window control circuit, responsive to the start signal from said start signal generator, for moving said window to its closed position to arrest street noises so as to ensure correct voice instruction recognition of said voice recognition unit, said window control circuit providing a control signal to said voice recognition unit to thereby place the same in a condition waiting for a voice instruction, said window control circuit, responsive to the completion signal from said voice recognition unit, for moving said window to its initial position; (c) a position sensor for providing a window closed position indicative signal to said window control circuit to thereby cause said window control circuit to generate the control signal to said voice recognition unit when the window reaches its closed position. - View Dependent Claims (15)
