Journal ArticleDOI

TL;DR: A new combination of optical tracking and ultrasound imaging that allows for a noninvasive, real-time view of most of the tongue surface during running speech is described.
Journal ArticleDOI
Functional segments in tongue movement.
TL;DR: This paper will discuss the independence of five proposed segments in the production of speech with high correlations between tongue segments would suggest passive biomechanical constraints and low correlations would suggest active independent control.
Journal ArticleDOI
Articulatory–acoustic kinematics: The production of American English /s/
TL;DR: This study documents in detail how jaw, tongue front, tongue back, lips, and the first spectral moment covary during the production of /s/, to establish how coarticulation affects this segment.
Journal ArticleDOI
Locus equations are an acoustic expression of articulator synergy
TL;DR: The study investigated the articulatory basis of locus equations, regression lines relating F2 at the start of a Consonant-Vowel (CV) transition to F1 at the middle of the vowel, and concluded that slopes and intercepts of acoustic locu equations are measures of articulator synergy.
Journal ArticleDOI
Patterns of tongue movement
TL;DR: Based on the analysis of 600 lingual transitions from an X-ray database of speech, it is shown that there are only two basic patterns of tongue movement, the pivot and the arch, which are independent of the starting and ending segments of a transition.
