Abstract

The invention discloses a sound source positioning method and device, and belongs to the technical field of communication. The method mainly comprises the steps of receiving a target audio signal, wherein the target audio signal comprises a noise audio signal; according to the target audio signal, determining a first signal spatial spectrum corresponding to the target audio signal, wherein the first signal spatial spectrum is used for representing the distribution state of audio signal spatial energy of the target audio signal; performing interference removal processing on the first signal spatial spectrum through a noise spatial spectrum corresponding to the noise audio signal to obtain a second signal spatial spectrum; and positioning the target audio signal according to the direction of the target spectrum peak in the second signal spatial spectrum.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a sound source localization method, device, electronic equipment and storage medium. Background technique [0002] In various communication devices and voice interaction systems, sound source localization can enable the pickup system to track the sound source of the signal it receives, and accurate sound source localization can effectively improve the quality of voice communication in noisy backgrounds. [0003] At present, the sound source localization usually obtains the spatial spectrum based on the signal received by the microphone array, and performs spectral peak search on the spatial spectrum, so that the direction corresponding to the spectral peak is the direction of the sound source. However, in the case of some interference factors such as many environmental noises, the obtained spatial spectrum is unstable, resulting in inaccurate determina...
