Finnish inserted vowels: a case of phonologized excrescence

Abstract

In this paper, I examine a case of vowel insertion found in Savo and Pohjanmaa dialects of Finnish that is typically called “epenthesis”, but which demonstrates characteristics of both phonetic excrescence and phonological epenthesis. Based on a phonological analysis paired with an acoustic corpus study, I argue that Finnish vowel insertion is the mixed result of phonetic excrescence and the phonologization of these vowels, and is related to second-mora lengthening, another dialectal phenomenon. I propose a gestural model of second-mora lengthening that would generate vowel insertion in its original phonetic state. The link to second-mora lengthening provides a unified account that addresses both the dialectal and phonological distribution of the phenomenon, which have not been linked in previous literature.
