Abstract
A voice-control system for motor vehicles has a plurality of spaced microphones emitting respective microphone signals, and an evaluation unit connected to the microphones. This unit serves for assembling correlation pairs from the signals of two of the microphones, calculating a correlation coefficient for each correlation pair, detecting an energy value for each microphone, detecting a respective delay time of a voice signal between a voice signal source and the each of the microphones, and selecting in dependence on current correlation coefficients of the correlation pairs, on the current energy values of the microphones, and on the current delay time of the voice signal to the microphones, that microphone whose signal is optimal as a basis for the operation of the voice-control system.
