Abstract

A speaker-phone device consisting of in and outgoing speech channels (U, I), connectable to a telephone line (T) via a forked coupling (9). The devices are connected to the speech channels (3, 7 and 12, 13) designed for the regulation of amplifier levels and speech direction in the speech channels. The device is connected to or comprised of a micro processor (10, 10') which controls regulation and exchange.<IMAGE>
