Coarticulation effects have been observed in the motion of the lateral pharyngeal wall (LPW) during speech. Pulsed ultrasound was used to measure the displacement of LPW during the trisyllables/aba/, /abi/, /iba/, /ibi/. The extent of vowel-consonant (VC) and consonant vowel (CV) motion was different depending on the other vowel.
