Explaining Final Obstruent Voicing in Lezgian: Phonetics and History

In Lezgian, a Nakh-Daghestanian language, final and preconsonantal ejectives and voiceless unaspirated obstruents are voiced in certain monosyllabic nouns. This article offers acoustic evidence confirming that the two coda-voicing series are indeed voiced in final position. Based on comparative evidence, it is demonstrated that this phonetically aberrant neutralization pattern is the result of a series of phonetically natural sound changes. Such ‘crazy rules’ (Bach & Harms 1972) undermine any direct phonetic licensing approach to phonology, such as LICENSING BY CUE (Steriade 1997).
