Zusammenfassung:	A sound source tracking method adapted to a video conference comprises: sending a first audio signal to a speaker by a host; performing an audio processing procedure according to the first audio signal to generate a second audio signal by a processor of the speaker; encoding the second audio signal and sending the encoded second audio signal to a sound source tracking camera by an encoding circuit of the speaker; playing the second audio signal to generate a far-end sound by the speaker; decoding the encoded second audio signal by the sound source tracking camera; recording a live sound by a microphone array, with the live sound including at least one of a local sound and the far-end sound; and performing a comparison procedure based on the live sound and the decoded second audio signal to determine a shooting direction of camera of the sound source tracking camera by the the sound source tracking camera.
