Guidelines

- prostudovat relevantní literaturu týkající se role šumových segmentů při srovnávání mluvčích
- zpracovat nahrávky (semi)spontánní řeči z databáze obecné češtiny od 60 mluvčích
- simulovat pásmovou propusť telefonního filtru
- provést manuální segmentaci cílových hlásek (s, š, x, ř̥)
- extrahovat akustické parametry, porovnat jejich vnitřní a vnější variabilitu vzhledem k mluvčímu ve standardních i telefonních nahrávkách a vyvodit závěry
