Abstract

Configuration enabling a group of users to hear and break in freely on a conversation to give an answer, around a telephone set, without having to manipulate or hold a receiver. The invention implements means modally different for both speaking and hearing functions, which means are selected as a function of the absence of any harmful interactive effect. Only one of these two functions, speech, occupies the acoustic space of the conference site.
