Lip and Jaw Articulation

Abstract

Introduction Lip and jaw or mandibular movements in speech production have been extensively studied (see e.g. Lindblom 1967; Perkell 1969; Lindblom and Sundberg 1971; Kelso et al. 1985; Ostry and Munhall 1994; Vatikiotis-Bateson and Ostry 1995; Ostry, Gribble and Gracco 1996), partly because they are more amenable to direct instrumental investigation than other speech articulators which often require invasive techniques. The types of investigations are numerous and include movement and kinematic studies (using e.g. cinefluorography, the X-ray microbeam system, strain-gauge and optoelectronic devices and electromagnetic midsagittal articulatory tracking devices), studies of the mandibular and..
