Guidelines

- prostudovat relevantní literaturu týkající se identifikace mluvčího a vyjadřování závěrů ve forenzní fonetice
- provést manuální segmentaci nahrávek min. 15 mluvčích z databáze obecné češtiny
- extrahovat hodnoty formantů u vybraných vokálů
- provést bayesovskou analýzu při různých velikostech a složeních populace a vyvodit závěry
