The present invention relates a method for localization of a speaker in a room in that at least one loudspeaker and at least one microphone array are located, comprising the steps of outputting sound by the at least one loudspeaker such that the sound is at least partly reflected by the speaker; detecting the sound output by the at least one loudspeaker and at least partly reflected by the speaker by the microphone array to obtain microphone signals for each of the microphones constituting the microphone array; and determining the speaker's direction towards and/or distance from the microphone array on the basis of the microphone signals.
