Document Type and Number:
WIPO Patent Application WO/2022/135131
Kind Code:
A1
Abstract:
A sound source positioning method and apparatus, and an electronic device. The method comprises: determining at least one candidate sound source azimuth in a pickup interval corresponding to an audio information acquisition sensor (101); for the at least one candidate sound source azimuth, obtaining a signal-to-noise ratio and a signal-to-interference ratio of the candidate sound source azimuth, and determining a weighting factor corresponding to the candidate sound source azimuth according to the signal-to-noise ratio and the signal-to-interference ratio of the candidate sound source azimuth (102); and determining a target azimuth of the sound source according to the weighting factor of the at least one candidate sound source azimuth (103). The accuracy of positioning a sound source in a multi-sound-source scene can be improved.
