Abstract: One object is to allow communication by sound/voice other than user speeches in voice chatting. A system according to an embodiment includes a plurality of terminal devices and a server communicatively connected to the terminal devices; and the system allows voice chat between users of the terminal devices. In the system, the terminal devices of the users who are members of a chat unit and participating in the chat unit perform the voice chat communication for implementing the voice chat in the chat unit. The terminal device of one user who is a member of the chat unit makes a play request for an audio file selected by the one user to the terminal device of another user who is a member of the chat unit based on an instruction from the one user, and the terminal device of the other user plays the audio file.

Abstract: A server according to one embodiment includes an information storage unit that store various types of information; a notification information transmission unit that transmits predetermined notification information to a terminal device of an invited user who is invited to a voice chat in response to receiving a voice chat initiation request from a terminal device of a requesting user; a state monitor unit that monitors whether the requesting user and the invited user are in an available state in which they are able to perform a voice chat; and a voice chat control unit that enables a voice chat communication between the terminal device of the requesting user and the terminal device of the invited user when the requesting user and the invited user are in the available state. The server serves as a voice chat management device that manages a voice chat between users who operate their terminal devices.
