Abstract
Abstract An audio interactive system including a plurality of terminals each having an audio input means for converting voices into aural signals and an audio output means for converting aural signals into voices, the plurality of terminals being connected to a communication line; and a server connected with the plurality of terminals via the communication line to perform collection and distribution of the aural signals, in which a conversation is made through voices between the plurality of terminals. The server comprises a buffer for temporarily storing the aural signals transmitted from the terminals, and a scheduler for controlling the distribution of the aural signals stored in the buffer.
