The Effect of Syllable Structure on Bidirectional Coarticulation

The goal of this research was to assess the effect of syllable structure and stop place on the strength of bidirectional coarticulation in VCV utterances. Frequencies of F2 transitions were measured at VC and CV boundaries in open (V.CV) and closed (VC.V) syllable forms in five speakers of American English. Medial stops varied across place and voicing (/bpdtgk/). Carryover and anticipatory coarticulation were measured by comparing the difference in F2 offsets of V1 (anticipatory) and F2 onsets of V2 (carryover) across four 'fixed' vowel (/i/, /e/, /u/, and /ɔ/) and two 'changing' vowel contexts (/i/, /ɔ/).
   Results showed a significant syllable x coarticulation interaction with closed syllables favoring carryover and open syllables favoring anticipatory coarticulation. Only alveolar stops /dt/ failed to reveal greater anticipatory than carryover effects in open syllables.
