Abstract (en)

[origin: DE19812697A1] The invention relates to a method and a device for operating a microphone system, especially in a motor vehicle, in accordance with the preamble to claims 1 and 6. To markedly improve the recording quality of the speech signal introduced into the system the invention provides for the speech sound to be detected in several different physical locations so as to track a virtual microphone location which is optimised in relation to a moving speech source. From the evaluation of variables such as operating time and/or phase and/or amplitude the individual microphone locations can be virtually weighted and the audio signals of the microphones can be added accordingly or combined in other ways.
