摘要

A system for acquiring speaker information by using voice feature information of a speaker and a method therefor are provided to extract the voice feature information from a voice of the speaker and acquire various information about the speaker from the extracted information. A GMM(Gaussian Mixture Model) generating unit(11) generates a GMM for inputted speaker-classified voice feature information. A speaker information deducing unit(12) deduces information about a specific speaker having a specific voice feature from the GMM and a UBM(Universal Background Model) constructed in each node of a decision tree.
