The invention relates to a method of detecting a speaker in an ACT telephone conference. The method includes a step 101), a step 102) and a step 103). The step 101) is that in the ACT telephone conference, an audience list is maintained at a conference participant end. The conference participant is informed that a speaking node is arranged as the emerging information of a new speaker by using a broadcast way when the new speaker emerges in conference participants. The step 102) is that the notice is replied by using the maintained audience list after the audience receives the information. Specific information of the new speaker node is inquired by a request packet delivered by an audience node.
