Original abstract

The present study focused on the perceptual effects of tonsillectomy using sound simulations, based on the earlier Finite Element (FE) modeling data. Of interest was whether different listener groups behave differently in perceptual analysis of simulated sound samples. Two groups of listeners were chosen: Musicians specialized in different instruments including singing, and speech students with training in perceptual analysis of human speaking voice. Samples with and without tonsils did not differ significantly from each other for voice quality (Paired Student's t-test, p > 0.05), due to differences in vowels. Timbre was significantly darker without tonsils (p=0.003 for the speech students, p=0.013 for the musicians). Musicians' and speech students' evaluations differed from each other (Unpaired Student's t-test, p=0.006 for quality and p=0.041 for timbre). No correlation between timbre and quality.

Tento příspěvek je zaměřen na subjektivní hodnocení hlasu po odebrání mandlí. Zvukové záznamy českých samohlásek byly získány pomocí výpočtového modelování na MKP modelech vokálního traktu. Cílem příspěvku bylo určit, jestli rozdílní posluchači hodnotí hlas před a po odebrání mandlí různě. Byly zvoleny dvě skupiny posluchačů: hudebníci vzdělaní ve hře na různé hudební nástroje a ve zpěvu, a studenti řeči trénovaní v hodnocení kvality mluveného hlasu. Z výlsedků vyplývá, že záznamy před a po odebrání hlasu se neliší v kvalitě hlasu (Paired Student's t-test, p > 0.05). Barva hlasu byly výrazně temnější po odebrání mandlí (p=0.003 pro skupinu studentů řeči, p=0.013 pro skupinu hudebníků). Hudebníci a studenti řeči se ve svém hodnocení odlišovali (Unpaired Student's t-test, p=0.006 pro kvalitu hlasu and p=0.041 pro barvu hlasu). Nebyl zjištěna korelace mezi kvalitou hlasu a jeho barvou.
