Abstract
A sound source tracking method adapted to an ongoing video conference comprising: obtaining a streaming signal of the video conference from an internet; performing a video conference procedure to obtain an audio signal from the streaming signal and send the audio signal to a speaker; performing an audio tracking procedure to obtain the audio signal outputted from the video conference procedure to the communication device and send the audio signal to a sound source tracking camera; playing the audio signal to generate a far-end sound; recording a field sound comprising at least one of the far-end sound and a local-end sound; and performing a comparing procedure to determine a shooting direction of the sound source tracking camera, wherein the shooting direction is adjusted so as not to shoot the speaker when a similarity of the far-end sound and the audio signal is greater than a threshold.
