Comparing apples to oranges - asynchrony in jaw & lip articulation of syllables

Svensson Lundmark, Malin LU orcid and Erickson, Donna (2023) 20th International Congress of the Phonetic Sciences p.1097-1101
Abstract
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 were found in timing between jaw opening and lip aperture opening, and the amount of difference varied as a function of syllable type (open/closed) and voicing/manner of the consonant. Our interpretation of the asynchronous patterns of lip and jaw articulation is that the jaw is the syllable articulator and the lips are the syllable onset/coda... (More)
