| Guidelines |
| - prostudovat relevantní literaturu a vypracovat přehled metodologie a dosavadních nálezů v oblasti forenzní fonetiky a využití formantových hodnot - zpracovat nahrávky alespoň deseti mluvčích v souladu se zásadami Pražského fonetického korpusu - provést manuální segmentaci vokálů - extrahovat statické i dynamické formantové hodnoty a dlouhodobé formantové distribuce - porovnat obecné i individuální tendence a vyvodit závěry |
