Abstract: A sound source localization method includes: obtaining a first audio frame and at least two second audio frames, wherein the first audio frame and the at least two second audio frames are synchronously sampled, the first audio frame is obtained by processing sound signals collected by the first microphone, the at least two second audio frames are obtained by processing sound signals collected by the second microphones; calculating a time delay estimation between the first audio frame and each of the at least two second audio frames; and determining a sound source orientation corresponding to the first audio frame and the at least two second audio frames through a preset time delay-orientation lookup table according to the time delay estimation between the first audio frame and each of the at least two second audio frames.
