Abstract:
A method of conducting a conference call, comprising: identifying a user (2) of a first communication unit (12) speaking during the conference call; transmitting data related to the identified speaker (2) to other communication units (14, 16, 28) being used by other users (4, 6, 8) participating in the conference call; the communication units (14, 16, 18) receiving the data related to the identified speaker (2) and displaying speaker data based on the received data related to the identified speaker (2). The speaker (2) may be identified by comparing the speech being spoken by the user with a voice profile for that user. Also described is a corresponding communication system, a caller identification module (21), and adapted communication units (12, 14, 16, 18).
