Abstract (en)

[origin: WO9957938A1] The invention relates to a method and a device for operating voice-controlled systems, such as communication and/or intercommunication systems in motor vehicles. According to the invention voice signals are received in a multiple microphone system and transmitted to at least one loudspeaker. The aim of the invention is to eliminate feedback with a method and device of this kind. To this end the invention provides for the voice signal or voice signal spectrum first to be subjected to a low-value DELTA F frequency shift before being transmitted to the loudspeaker(s) or the input of a voice-controlled device.
