Abstract
To examine how people react to palatalized articulation, we used one cleft palate speech (CPS) sample of palatalized articulation that was purchased in Japan and one recorded sample of speech from a non-cleft palate individual. Study design The two speech samples were rated by 137 native listeners. Each participant rated the set of speech samples for 10 features using a 10-point scale. Alpha factor analysis was performed. Results Two factors were extracted from the entire set of features with alpha factor analysis. Conclusions Although native listeners could not distinguish between CPS and non-CPS using the psychometrical measurements applied in this study, this method of analyzing speech represents a useful technique for planning treatments in cleft disorder patients.
