Routes to lenition: an acoustic study

Vowel lenition and its link with coarticulation have been the subject of extensive debate in the literature. The aims of the present paper are to demonstrate how vowel lenition and coarticulation are linked in Cypriot Greek (henceforth CG), to determine the nature of vowel lenition, and to illustrate how vowel lenition and coarticulation result from aerodynamic phenomena. Eight speakers were recorded producing utterances ending in either /i/ or /u/. Acoustic measures such as V(1)F2 and stop duration were employed to determine whether lenition of the vowels results in coarticulation with the preceding consonant. Results show that there is extensive stop-vowel coarticulation in CG and that stop production is as variable as vowel production, with full vowels never co-occurring with canonical consonants, indicating the existence of two routes to lenition in CG. These findings suggest that lenition in the final syllable is a consequence of the supralaryngeal articulation coupled with a marginal glottal setting.
