A voice communication system, in which the real space is associated with a virtual space and a relative location and direction of a communication partner in the real space can be grasped as bodily sensations, is provided. A client 201 comprises a GPS receiver 231 and a magnetic sensor 232 which detects a location of a user of the client 201 itself in the real space, a presence provider 222 which sends the location detected by the detection means to a server apparatus, a space modeler 332 which calculates a location of the user in the virtual space based on the location of the user himself and locations of the other users in the real space, and an audio renderer 216 which controls sound effects based on the locations of the users in the virtual space.
