articulatory dynamics

A branch of ARTICULATORY PHONETICS which studies the forces underlying articulatory movements, such as the role of the jaw, the contribution of the relevant muscles, and variations in subGLOTTAL air pressure. The subject aims to determine the quantitative relations among the forces generated by the articulatory muscles, the inertial and resistive properties of the articulators against which the forces are working, and the resulting movements.
