U rozpoznávání mluvčího (SRE) došlo v minulých letech k podstatnému teoretickému a algoritmickému pokroku. Projekt se soustředí na adaptaci algoritmů pro specifické potřeby policejních a zpravodajských složek, tak aby (1) poskytovaly precizní ale jednoduché zobrazení výsledků tak, aby zodpovědní pracovníci získali včas potřebnou informaci a udrželi si rychlost reakce proti hrozbám a ve vyšetřování, (2) je bylo možné dotrénovat na cílových datech uživatele a podstatně tak zvýšit jejich úspěšnost.

Description in English
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.
