Outline 第一,鉴于有些同学不了解SRE的相关工作,所以我先把双周任 务时候我报告的东西快速回顾一下,让大家有个直观的印象 第二,我会总结一些最新的研究(基本是CASF2018有关SRE的 内容)要点,以及我的一些思考和问题

Outline • Introduction • The i-vector methodology of speaker recognition • The d-vector methodology of speaker recognition • The end-to-end methodology of speaker recognition • Inter-speaker variability in speaker recognition • Example of variations in speaker recognition • State-of-art approach in SRE
Introduction Definition: It is the method of recognizing a person based on his Voice Speaker identification Speaker verification Speaker diarization Speaker recognition Text dependent Text independent pen set Close set
Introduction • Definition: It is the method of recognizing a person based on his voice Speaker recognition Speaker identification Speaker verification Speaker diarization Text dependent Text independent Open set Close set
Speaker Identification Definition: Determine whether unknown speaker matches one of a set known speakers One-to-many mapping Often assumed that unknown voice must come from a set of known speakers-referred to as close-set identification Adding hone of the above option to closed -set identification gives open-set identification nose voice is this?
Speaker Identification • Definition: Determine whether unknown speaker matches one of a set known speakers • One-to-many mapping • Often assumed that unknown voice must come from a set of known speakers – referred to as close-set identification • Adding “none of the above” option to closed-set identification gives open-set identification
