Voiced stop prenasalization in two dialects of Greek

This study examined the phonetic realization of voiced stops in the Cretan and Thessalonikan dialects of Modern Greek. Six males and six females of each dialect were recorded in a sentence-reading task. Duration and amplitude were measured to compare the degree of nasality of voiced stops to that of nasals in different phonetic contexts. Results showed that amplitude changes during the voicing bar of the voiced stops varied both within and across speakers. In some instances, there was consistently low amplitude throughout the voicing bar (characteristic of voiced stops), whereas in other instances, there was high amplitude at the closure onset followed by decreasing amplitude toward the burst (characteristic of prenasalization). By contrast, nasals had consistently high amplitude throughout the murmur. The mixed-effects models suggest that there were complex and interactive influences of dialect, gender, prosodic position, and stress in realizing prenasality in the voiced stops. In particular, Cretan male speakers showed the least clear tendency of prenasalization consistent with earlier impressionistic studies. Furthermore, productions of Cretan males showed less prenasalization than those of females in both prosodic positions. The procedures in this study can be used to describe prenasalization in other dialects or languages where prenasalization has been observed.
