ABSTRACT:
A conference speech-channel forming method and its conference telephone system, in which an extension telephone set to be operated by an operator as the chairman of a conference is connected in a predetermined logical manner through a private branch exchange to a plurality of extension telephone sets to be operated by a plurality of operators as the participators of the conference to form conference speech channels between these extension telephone sets. That is, the conference speech channels are formed so that (a) a voice signal issued from the extension telephone set of the chairman operator is parallelly transmitted in one way to all the plurality of extension telephone sets of the plurality of participator operators, and (b) voice signals issued from the plurality of extension telephone sets of the participator operators are added together at a voice adder circuit and then transmitted to the extension telephone set of the chairman operator. In this case, mutual speeches between the chairman and participators are allowed only in a one-to-plurality relationship. In addition, mutual speeches between the participators other than the chairman are restricted. Thus, even in the event where the number of participators in a conference is large, the chairman operator can smoothly expedite the proceedings of the conference.
