An apparatus with a speech control unit includes a microphone array having multiple microphones for receiving respective audio signals, and a beam forming module for extracting a speech signal of a user, from the audio signals. A keyword recognition system recognizes a predetermined keyword that is spoken by the user and which is represented by a particular audio signal and is arranged to control the beam forming module, on basis of tie recognition. A speech recognition unit creates an instruction for the apparatus based on recognized speech items of the speech signal. As a consequence, the speech control unit is more selective for those parts of the audio signals for speech recognition which correspond to speech items spoken by the user.
