Abstract

The embodiment of the invention discloses a sound source positioning method and device and electronic equipment. A specific embodiment of the method comprises the following steps: respectively acquiring signal characteristic parameters of sound emitted by a sound source set to be positioned by using each array unit in a microphone array to obtain signal characteristic parameter vectors; according to the signal characteristic parameter vector, determining an orientation distribution vector of sound sources in the sound source set in each orientation; and determining the orientation of each sound source in the to-be-positioned sound source set according to the orientation distribution vector. The embodiment of the invention can achieve more accurate sound source localization.

Description

technical field [0001] The present disclosure relates to the technical field of information processing, and in particular to a sound source localization method, device and electronic equipment. Background technique [0002] With the development of technology, products with voice collection and processing functions are welcomed by more and more users. When these voice products process the collected voice information, in order to achieve a better voice processing effect, it is usually necessary to first locate the sound source. [0003] However, the current sound source localization algorithm usually has poor positioning accuracy when the size of the microphone array used is limited, and the positioning accuracy decreases significantly with the increase of reverberation, making it difficult to locate and track multiple sound sources at the same time. Contents of the invention [0004] This Disclosure section is provided to introduce a simplified form of concepts that are de...
