Conventional elevators comprise a console for entering control information, more particularly, via key depression. To make the known control arrangements simpler and more flexible to use by the user, the invention provides means for audio recording and a speech analysis unit, while a control unit controls the elevator in accordance with entered speech commands. According to a further embodiment of the invention, speech commands also include indirect location descriptions which are assigned to floors via the database of the building. Also a dialogue facility may be provided, for example, for commands that are not understood or are not unambiguous.
