A method for controlling a voice-controlled voice direction recognition unit for a digital telephone station, which can be connected to termination units having different hybrid attenuations. The method prevents self-interruption in the transmission side due to an excessively low hybrid attenuation. This is achieved by providing a counter unit that identifies the switching occurrences of the voice direction recognition per time unit and, when a predetermined number is exceeded, that causes the voice direction recognition unit to connect an auxiliary attenuation element into every voice channel. The method can be utilized in digital telephone stations whose termination units are located in an appertaining switching system.
