Control device for controlling the starting a vehicle in response to a voice command
 A device for sensing whether a driver has been drinking by analyzing the driver's voice, which includes a parameter extractor for producing a parameter corresponding to a linear prediction coefficient-cepstrum coefficient extracted from a digital signal obtained by converting the sound of the voice command, a storage device for storing a reference parameter extracted from the voice of the driver when the driver is sober, a comparator for comparing a current parameter extracted by the extractor with the reference parameter so as to produce a difference signal representing the deviation, and a decision circuit for determining whether the driver has been drinking in accordance with the deviation value. The parameter extractor generates the linear prediction coefficient-cepstrum coefficient after producing a linear prediction coefficient by performing auto-correlation on the digital voice signal.
