A method of operating a voice control system in an internal space and voice control system

The present invention relates to a method of operating a voice control system in an internal space (16), wherein the interior space (16) comprises at least a first zone and a second zone. In the method of acoustic raw data in the internal space (16) are detected and on the basis of the raw data an acoustic signal separation is performed. In this first zone the raw data are generated that are associated with the first zone, second zone and the raw data associated with the second zone. Furthermore, each keyword recognition wherein it is determined whether the first or second zone raw data include a specific keyword is made for the first and second raw data zone. When the first and the second zone raw data include the keyword, the zone raw data can be accurately determined a zone as input raw data through a speaker localization. a voice input is finally detected based on the determined raw data input and on the basis of the speech input, a control signal is generated.
