ABSTRACT:
The invention relates to a method of controlling function units of a motorcar or of devices (1a,1b) installed in a motorcar, via speech signals, in which acoustic signals occurring in the motorcar, which contain noise signal portions that depend on the operating state and/or operation environment of the motorcar, and speech signal portions, as the case may be, are applied to a speech recognition system (3) and the speech recognition system (3) uses acoustic references (8) which are selected and/or adapted in dependence on detected data of the operating state and/or operation environment. The invention is not restricted to speech control in the domain of motorcars.
