Abstract
A device for operating a microphone system, particularly in a motor vehicle, detects speech sound in several different physical locations to track a virtual microphone location, which is optimized in relation to a moving speech source. From the evaluation of variables, such as operating time, phase and/or amplitude, the individual microphone locations are virtually weighted, and the audio signals from the microphones are added or otherwise combined.
