A CINERADIOGRAPHIC STUDY ON THE MOVEMENT OF THE SOFT PALATE DURING PHONATION OF SPEECH SOUNDS

概要

Much research has been done on the movement of the soft palate during phonation. Most of it, however, has been studies on movement during the phonation of vowels and not on movement during consonant phonation. Furthermore, only a instantaneous phase of the movement was observed in those studies, and so far little observation has been done on the continuous course of the movement of the soft palate. Movements of the vocal tract are usually observed by the following methods : (1) measurement of nasal air pressure, (2) radiographical methods, and (3) electromyographical methods. In the authors case, the movement of the soft palate during phonation of speech sounds was observed using the high voltage cineradiography with electronic image amplifier, analysing the speech sounds recorded simultaneously on a sonagram.
