The aim of this study is to examine variability in V-to-V transconsonantal coarticulatory effects as a function of stress. Previous studies have documented greater coarticulatory effects of the stressed vowel on the unstressed suggesting that the unstressed vowel is coproduced more with the neighbouring stressed vowel. Evidence of such coarticulatory behaviour is examined using articulatory data recorded with the technique of electropalatography (Reading EPG system). The speech material consisted of Greek disyllabic real words containing Vowel- Consonant-Vowel (VCV) sequences with V = /i, a/ and C = /p,t,s/. Stress placement was on V1 or V2. The results provided evidence of greater coarticulatory effects of the stressed vowel on the unstressed vowel in both the anticipatory and carryover directions. However, these effects were not uniform but were systematically modified by factors such as the identity of the intervocalic consonant and speaker-specific strategies.
