Perci: A Method for Rating Palatal Efficiency

Abstract

This paper describes a new, simple technique for instantaneously rating velopharyngeal campeteng) during speech. The instrument, designed on the basis of data obtained from aerodynamic studies, provides an index of palatopharyngeal closure. Results from model-studies and 75 cleft palate subjects demonstrate how the instrument is used to differentiate between problems related to velop/zavjmgeal closure and those resulting from other variables which often influence the performance of speakers with cleft palate.
