Abstract This acoustic study investigated the extent and nature of vowel-to-vowel coarticulation in English trisyllabic utterances ( / bV1b E bV3b / ) where both V1 and V3 were either / A / or / i / . Primary stress was assigned to either the first or third syllable , and secondary stress was assigned to the other syllable . The study revealed considerable variability among the four speakers in the systematic ef fects of non-adjacent vowels on one another . The most important result is that coarticulatory ef fects can , in some instances , extend beyond the bounds that previous research had assumed ; both carry-over and anticipatory ef fects extend from one full vowel , through the medial schwa , and into the midpoint of the other full vowel . In fact , for one speaker , ef fects of V3 can be seen as early as V1 onset of / A / . This result indicates that the foot does not define the domain over which coarticulatory ef fects operate . Finally , this study found no evidence of greater carry-over than anticipatory effects .
