Dialectal effects on the perception of Greek vowels

This study examined cross-dialectal differences on the perception of Greek vowels. Speakers of Standard Modern Greek (SMG) and two dialectal areas (Crete, Kozani), all with five vowels in their systems, chose best exemplar locations (prototypes) for Greek vowels embedded in a carrier sentence spoken by a speaker of their dialect. The results showed that SMG, Cretan and Kozani vowels were well separated in the perceptual space. At the same time, there were dialect-induced differences in the positioning and distances between vowels as well as in the total space area covered by each dialect. The organisation of perceived vowel space therefore seems to be dialect-specific, a finding which is consistent with production studies examining the organisation of the acoustic vowel space.
