Abstract: A teleconference system includes an audio data receiving section, a group information holding section, and an audio controller. The audio data receiving section receives audio data obtained by multiple terminal apparatuses of multiple users who participate in a conference. The group information holding section holds group information indicating multiple groups. The groups are obtained by grouping the users of the terminal apparatuses. Any of the terminal apparatuses is referred to as a certain terminal apparatus. Each of the groups includes one or more users. The audio controller controls volumes of sound output of the audio data independently for the respective groups based on the group information held by the group information holding section. The audio data is received by the audio data receiving section.
