Comparing apples to oranges - asynchrony in jaw & lip articulation of syllables
This study examines jaw and lip aperture characteristics of syllables. High correlations were found between velocity and displacement of opening/closing of lips and jaw, similar to previous studies. However, lip aperture opening velocity changed as a function of manner and voicing of syllable onset while jaw opening velocity, except for a plosive onset, did not change. In addition, differences wer
