Sound source positioning method and device

Abstract

The invention relates to a sound source positioning method and device. The sound source positioning method comprises the steps: acquiring a first voice signal acquired from a sound source by a first microphone array and a second voice signal acquired from the sound source by a second microphone array under the condition that a sound source environment has at least two microphone arrays; determining a first sound source angle of the sound source relative to the first microphone array according to the first voice signal, and determining a second sound source angle of the sound source relative to the second microphone array according to the second voice signal; acquiring relative position information of the first microphone array and the second microphone array; and determining sound source position information of the sound source according to the relative position information, the first sound source angle and the second sound source angle. According to the sound source positioning method and device disclosed by the invention, the microphone array can be randomly placed, so that flexible microphone placement selection is obtained, deployment and maintenance are facilitated, and the advantages of multiple microphones are fully played.

Description

technical field [0001] The present disclosure relates to the field of audio technology, and in particular, to a sound source localization method and device. Background technique [0002] Now that 4G mobile network has been popularized, Wi-Fi and mobile network have launched Wi-Fi 6 and 5G next-generation communication standards one after another. to thrive. With the impact of the global epidemic, driven by many business scenarios such as online conferences and online education, people have higher requirements for the sound quality of calls in conferences. In the related technology, there is a microphone array, which is composed of multiple microphones. It can use beamforming (beamforming) algorithm to achieve voice enhancement. It can improve the sound quality of calls for small and medium-sized meetings and meet the needs of calls. For medium and large-scale meeting scenes, it often cannot be effectively covered. However, by increasing the number of microphones arranged i...

There is a microphone array in the related technology, which is composed of multiple microphones. It can use beamforming (beam forming) algorithm to achieve voice enhancement. It can improve the sound quality of calls for small and medium-sized meetings and meet the needs of calls. For medium and large-scale meeting scenes, it often cannot effectively cover

By increasing the number of microphones arranged in the conference scene, although the coverage can be improved, it is usually only a simple route selection for the signals collected by the multiple microphones arranged, and the advantages of multiple microphones are not fully utilized.
