Description
Summary:Examined is the stability of upper lip-jaw interarticulator timing across a wide range of speaker-selected rates. To determine if phase angle is stable across changes in rate, the relationship between jaw cycle duration & the angle on the jaw phase plane where the upper lip begins downward movement toward bilabial closure is studied. Native speakers of English (N = 8, aged 50-78) were recorded under six rate conditions & inferior-superior movements of the upper lip, lower lip, & jaw were transduced. Five of the eight Ss exhibited significant changes in phase angle across changes in speaking rate, indicating that interarticulatory timing relationships do not remain constant across rate changes. 2 Figures, 43 References.
