Abstract : Vowel reduction may involve phonetic reduction processes, with non reached targets, and/or phonological processes in which a vowel target is changed for another target, possibly schwa. Coratino, a dialect of southern Italy, displays complex vowel reduction processes assumed to be phonological. We analyzed a corpus representative of vowel reduction in Coratino, based on a set of a hundred pairs of words contrasting a stressed and an unstressed version of a given vowel in a given consonant environment, produced by 10 speakers. We report vowel formants together with consonant-to-vowel formant trajectories and durations, and show that these data are rather in agreement with a change in vowel target from /i e ɛ o ɔ u/ to schwa when the vowel is a non-word-initial unstressed utterance, unless the vowel shares a place-of-articulation feature with the preceding or following consonant. Interestingly, it also appears that there are 2 targets for phonological reduction, differing in F1 values. A “higher schwa” – which could be considered as /ɨ/ – corresponds to reduction for high vowels /i u/ while a “lower schwa” – which could be considered as /ə/ – corresponds to reduction for mid- high and mid-low vowels /e ɛ o ɔ/. /a/ is probably not affected by phonological reduction, possibly due to the longer duration of the consonant to vowel trajectory for low vowels. Altogether, the Coratino vowel system appears to evolve from a 7-vowel system /i e ɛ o ɔ u a/ for stressed configurations to a 3-vowel system /ɨ ə a/ for the most reduced configurations.
