| Guidelines |
| - prostudovat relevantní literaturu a vypracovat přehled metodologie a dosavadních nálezů v oblasti tvorby a ovládání hlasu (základní frekvence) a jejím využití ve forenzní fonetice
- zpracovat nahrávky čtené a spontánní řeči z Pražského fonetického korpusu (manuální segmentace sonorních intervalů, oprava kontury F0) - provést extrakci opravených hodnot F0, výpočet základních statistických údajů (střední hodnoty, rozptyl, distribuce hodnot) a porovnat rozlišitelnost mluvčích v jednotlivých typech materiálu - porovnat obecné i individuální tendence a vyvodit závěry |
