Anotace:
Projekt o Rozpoznávání mluvené řeči v reálných podmínkách. Projekt navazuje na předchozí grantově podporovaný výzkum, v němž se řešitelskému týmu podařilo vyvinout a částečně i realizovat základní metody rozpoznávání řeči v českém jazyce. Aby však mohly být úspěšně nasazeny v nejvíce žádaných aplikacích, jako jsou přepisy hovorů, záznamů diskusí nebo jednání v soudních síních, musí být pozornost zaměřena na analýzu a modelování běžné mluvené (hovorové) řeči zaznamenávané v reálných podmínkách za přítomnosti šumu, hluků, případně dalších mluvících osob.
