| Description
| - Článek se zabývá výzkumem vlivu vynětí mandlí na poslechovou kvalitu a zabarvení hlasu. Počítačově byla simulována foance 5-ti českých samohlásek před a po operaci mandlí. K simulacím byla použita metoda konečných prvků pro modelování vokálního traktu člověka. Velikost a tvar mandlí byl odhadnut z klinických údajů. Generovaný akustický tlak byl transformován do zvukových záznamů, které byly hodnoceny poslechem zkušenými, vyškolenými posluchači. Ze záznamu byly též vyhodnoceny formantové frekvence. Záznamy před a po operaci mandlí se významně nelišily v kvalitě hlasu, formant F3 byl významně nižší a barva hlasu byla hlubší po vynětí mandlí. Tudíž vliv operací mandlí na hlasovou kvalitu je slyšitelný, a to alespoň v případě mandlí větších rozměrů . (cs)
- This study aimed to investigate the effects of a tonsillectomy on the perceived overall voice quality and timbre. Computer simulations of five Czech vowels were made, including both the calculated resonance effects of large tonsils (size 1,6cm3) and the resonances without tonsils. The simulations were made using a finite element model of the vocal tract, based on magnetic resonance images. The size and shape of the tonsils were ascertained from clinical data. The generated pressure outputs were transformed into sound records presented to 10 trained listeners. Formant frequencies of the simulated samples were measured. The samples with and without tonsils did not differ significantly from each other in voice quality. F3 was significantly lower and the timbre was darker without tonsils. Thus, the effects of tonsillectomy on voice may be perceptible, at least in the case of large tonsils.
