Effects of extended speaking on resonance of patients with cleft palate.
Groups of listeners and rating scales were used to study the effects of extended speaking on resonance and voice quality in eight adults with cleft palate and mild to moderate hypernasality and a matched group of noncleft adults, with normal resonance and voice quality. Authors interpret their findings as indicating that resonance changes were greater and vocal quality changes less, for the cleft group, but that changes were not extensive nor always in the direction of increased hypernasality or decreased vocal quality.
