PROBLEM TO BE SOLVED: To equally give every speaker an opportunity to speak and to realize smooth replacement of speakers.SOLUTION: A movement detection section 103 detects a movement of a conference participant. A next utterance recommendation value calculating section 104 calculates a next utterance recommendation value showing priority of utterance of a conference participant on the basis of a speaker replacement history and a movement of a conference participant. A sound pressure calculating section 108 adjusts a sound pressure level of a voice of a conference participant on the basis of the next utterance recommendation value. Thus volume of a voice of a conference participant who does not speak for a while or who nods or moves his/her hands can be turned up, which equally gives every conference participant an opportunity to speak and realizes smooth replacement of speakers. |
