This study focuses on changes in the vowel system of contemporary Mišótika Cappadocian. It presents an acoustic analysis of the vowels of Mišótika, based on recordings of 16 native speakers from two different Cappadocian communities in Northern Greece. Our analysis shows that the current vowel system diverges significantly from the older one. Moreover, there are significant differences between the two Cappadocian speech communities, which are the result of dialect contact under different sociolinguistic conditions. Finally, gender also seems to be a significant sociolinguistic parameter, as male speakers seem to be one step ahead in the process of linguistic change.
