1. A voice call system that includes a plurality of voice telecommunication terminals, a content server to provide a sound source for each of the plurality of voice telecommunication terminals, and a presence server to manage positions of users of the plurality of voice telecommunication terminals and a sound source provided by the content server in a virtual space, the voice call system comprising:

  • a presence acquisition unit that acquires information about positions of users of the plurality of voice telecommunication terminals and the sound source provided by the content server in a virtual space from the presence server; and

    an audio renderer provided for each of the voice telecommunication terminals, wherein the audio renderer performs a process for applyinga stereophonic process to voice data for each of voice telecommunication terminals other than a voice telecommunication terminal corresponding to the audio renderer in accordance with a relative position between each of users of the other voice telecommunication terminals and a user of the voice telecommunication terminal corresponding to the audio renderer, in which the presence acquisition unit acquires position information to specify the relative position anda stereophonic process to acoustic data from a sound source provided by the content server in accordance with a relative position between the sound source and the user of the voice telecommunication terminal, in which the presence acquisition unit acquires position information to specify the relative position; and

    a process for synthesizing the stereophonically processed voice data for each of the other voice telecommunication terminals with acoustic data for the sound source to generate voice call data for the voice telecommunication terminal corresponding to the audio renderer; and

    wherein the presence server includes;

    a position information management unit that determines a position of the sound source in a virtual space in terms of each of the plurality of voice telecommunication terminals so that a user of a relevant voice telecommunication terminal can distinguish the position of the sound source in the virtual space from positions of users of the other voice telecommunication terminals.
