ABSTRACT:
A system and method to estimate a location of a speaker who produces a sound signal even in a non-stationary noise environment. The system includes a signal input module receiving a first sound signal from an outside; an initialization module preparing a sound map, on which a spatial spectrum for the first sound signal, produced from at least one fixed sound source and received by the signal input module, is arranged, and estimating a location of the fixed sound source; a storage module storing information about the estimated location of the fixed sound source; and a speaker's location estimation module estimating a location where a second sound signal is produced using information about the spatial spectrum for sound signals including the first sound signal received by the signal input module and the information about the estimated location of the fixed sound source.
