Sound source localization device, sound source localization method, and program

Abstract:

A sound source localization device includes: a sound receiving unit that includes two or more microphones; and a sound source localization unit that transforms a sound signal received by each of the microphones into a frequency domain, models a steering vector through Fourier series expansion of an N-th (here, N is an integer equal to or larger than "1") order for the transformed sound signal of the frequency domain for each of the microphones, calculates a steering vector of an arbitrary angle using the modeled steering vector, and performs localization of a sound source using the calculated steering vector of the arbitrary angle.
