Info

Hypernasality • Too much sound resonating in the nasal cavity • Usually due to VPI or fistula • Most perceptible on vowels Hypernasality • Voiced oral consonants become nasalized (m/b, n/d, etc.) – Obligatory distortion • Other consonants may be substituted by nasals – Compensatory production 8
Hyponasality • Not enough nasal resonance on nasal sounds (m, n, ng) • Due to nasal obstruction • Nasal phonemes sound similar to oral cognates (b/m, d/n, g/ng) • Also noticeable on vowels Cul de Sac Resonance • Sound resonates in a cavity (oral, pharyngeal or nasal), but cannot get out • Due to blockage in the vocal tract 9
