Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] At present, the traditional speaker separation method mostly detects the endpoint of the audio file, retains the audio file corresponding to the speech segment, and then performs feature extraction on the audio file to obtain multiple voiceprint features, and clusters all voiceprint features. Then compare each type of voiceprint features with the voiceprint features in the voiceprint f...

Abstract

The invention provides a speaker separation method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the detection of a person in a video frame, and obtaining the position of a person in the video frame; performing sound source positioning on the audio segments corresponding to the video frames to obtain sound source positions; and based on the relative position relationship between the personnel position and the sound source position, carrying out speaker separation on the audio band. According to the speaker separation method and device, the electronic equipment and the storage medium provided by the invention, the influence of environmental noise and the voiceprint feature difference degree of different roles of speakers can be avoided, and then speaker separation can be accurately carried out on the audio band based on the relative position relationship between the speaker position and the sound source position.

Description

technical field [0001] The invention relates to the field of intelligent voice technology, in particular to a speaker separation method, device, electronic equipment and storage medium. Background technique [0002] Speaker separation refers to dividing the audio data belonging to each speaker in an audio file, merging the audio data of the same speaker into one category, and separating the audio data of different speakers. [0003] At present, speaker separation is mostly achieved by extracting the voiceprint features of each speaker in the audio file, and comparing the voiceprint features of each speaker with the voiceprint features in the voiceprint feature library. However, the audio file may contain multiple voiceprint features corresponding to different speakers, and the voiceprint features of some speakers are not stored in the voiceprint feature database, which leads to the problem of low speaker separation accuracy. Contents of the invention [0004] The inventio...
