title: Comparison of Nasometer and listener judgments of nasality in the assessment of velopharyngeal function after pharyngeal flap surgery.
abstract: This study examined the relationship between nasalance scores as derived from the Model 6200 Nasometer and listener judgments of perceived nasality for individuals with pharyngeal flaps. Sixteen individuals with pharyngeal flaps read a speech sample consisting of seven sentences for which associated nasalance scores were obtained. In addition, 10 trained listeners were asked to judge the subjects' audiorecorded speech samples for the degree of both hypernasality and hyponasality using two 6-point scales. The mean judges' ratings of hypernasality did not increase systematically with increasing nasalance scores or with decreasing hyponasality ratings. However, as the nasalance scores associated with nasal loaded sentences increased, a systematic decrease in listener perception of hyponasality occurred.
