Abstract
|
|
|
In this paper, I investigate the acoustic correlates of a vowel¢¥s coarticulatory dynamics manifested in preceding and following consonants along two dimensions of the vocal tract: place of articulation and degree of constriction. Two dimensional coarticulation is not necessarily executed either concomitantly or proportionally, and the modification induced by coarticulation with a vowel in CVC structures is merely constriction location. This is consisten with the observation that C-to-V place assimilation does not accompany consonant lenition in phonology, which suggests that phonetic nature is effectively reflected in phonological patterns.
Keywords: C-to-V coarticulation, assimilation, horizontal dimension, vertical dimension
