Title:
SOUND SOURCE LOCALIZATION METHOD AND APPARATUS, AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/056905
Kind Code:
A1
Abstract:
A conference speech display system, a sound source localization method and apparatus, a conference system, and a sound pickup device. The method comprises: acquiring a multi-channel voice signal by means of a directional microphone array (S101); determining, according to array shape information and microphone directional information, a steering vector comprising phase information and amplitude information (S103); and determining sound source direction information according to the steering vector and the voice signal (S105). By using such a processing mode, the phase information and amplitude information are considered while the steering vector is determined, such that the accuracy of sound source localization can be effectively improved.
