Zusammenfassung:	The scope of the present invention is a device for detecting the source of a voice, which device comprises microphone means (2; 2a, 2b, 2M) for receiving a voice signal and detecting means for detecting the voice from the received voice signal. The device comprises means (15, 17) for determining the direction of arrival of the received signal, means (17) for storing the assumed direction of arrival of the voice of a certain source and means (18) for comparing the direction of arrival of said received signal with said assumed direction of arrival. The device further comprises means (18) for indicating that the source of the voice is said certain source when the comparison proves that the direction of arrival of said received signal matches with said assumed direction of arrival within a certain tolerance.
