<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for reproducing sounds with realistic sensation in which the influence of movements of heads of both communication parties when sound source units such as mouths or sound collecting units such as ears in such a case where the heads of both the communication parties move in conversation in communication between remote places. <P>SOLUTION: In communication between communicators each provided with a sound source unit for emitting sounds and a sound collecting unit for collecting sounds, this method reproduces sounds equivalent to an open type sound collecting mode in which the sound collecting unit is not relatively fixed on a sound source unit, even at least any one of the communicators has a headset type sound collecting mode in which the sound collecting unit is relatively fixed on the sound source unit. In this method, when a speaking party's communicator moves spatially, the voice and sound collected with the sound collecting unit of the speaking party's communicator are converted by an inverse head transmission function for obtaining changes in voice and sound equivalent to a case of collecting voice and sound with a sound collecting unit fixed on a virtual position from the change in the sound source unit by using information indicating the spatial movement of the sound source unit of the speaking party's communicator. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
