Patent attributes
A contributor who is one of a number of participants divided into groups at telephone terminals is identified by recognizing the contributor voice during a teleconference managed by a conference device connected to the terminals. After the voice of the contributor received by the conference device is identified, an identifier of the identified contributor is broadcast from the conference device to the terminals and reproduced at the terminals. The contributor is introduced to the other participants, automatically or on demand, for example by a voice or visual message including the contributor name. The conference device can be included in one of the terminals; for example, the identifier identifies a contributor other than the regular user of a communicating telephone or mobile radio telephone.
