Past few years have witnessed a substantial progress in theory and algorithimization of speaker recognition (SRE). This project aims at adaptation of SRE algorithms for specific needs of police and intelligence services, in order to (1) provide precise but easy-to-understand visualization so that responsible personnel obtains timely information needed to cope with threats and to speed up investigation, (2) be able to adapt systems to target user data and substantially improve their performances.
