Sound source separation device

Abstract

A sound source separation device according to an embodiment of the present disclosure includes a plurality of microphones, a matrix unit, and an output unit. The plurality of microphones may receive a plurality of microphone input signals transmitted from a plurality of sound sources. The matrix unit generates an objective function according to an estimated source vector and an estimated noise vector estimated based on the plurality of microphone input signals, and replace a first term and a second term included in the objective function using a log-likelihood function to estimate a demixing matrix. The output unit provides output vectors calculated based on the microphone input signals and the demixing matrix.
