Title:
METHOD, DEVICE, AND APPARATUS FOR PERFORMING VOICEPRINT CLUSTERING ON THE BASIS OF SAMPLE SIZE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/051505
Kind Code:
A1
Abstract:
A method, device, and apparatus for performing voiceprint clustering on the basis of sample size, and a storage medium. The method comprises: a processor storing, in a cache module, a voiceprint sample set awaiting clustering, and determining whether or not the voiceprint sample set is a large sample set having a sample size exceeding a preset sample size threshold; if so, determining, from a storage module, a voiceprint clustering model corresponding to the large sample set to serve as a target voiceprint clustering model; and performing clustering on the voiceprint sample set on the basis of a trained partitional clustering algorithm in the target voiceprint clustering model, and outputting a clustering result pertaining to the voiceprint samples. The method uses different clustering models for different sample sizes, and shortens clustering time for large voiceprint sample sets by means of partitional clustering, thus improving clustering performance.
