Dynamic Palatography

Abstract

Abstract This report highlights general implications stemming from two studies of normal subjects’ articulation via dynamic palatography instrumentation. The Kydd-Belt palatal device was utilized in association, first, with cinematographic recording of a light palatal analog, then with a 12-channel multiple-event counting system; a 13th channel recorded the presence of laryngeal tone, while a 14th channel recorded time segments. Patterning of contacts, ‘approach’ patterns, seating, and release behavior, as well as attempts to associate contacts with laryngeal tone were examined. The results are discussed in terms of their general implications to the act of articulation, the behavior of the tongue apex and lateral borders, symmetry of contacts, and sequencing of linguapalatal contacts.
