The emergence of obstruents after high vowels

While a few cases of the emergence of obstruents after high vowels are found in the literature (Burling 1966, 1967, Blust 1994), no attempt has been made to comprehensively collect instances of this sound change or give them a unified explanation. This paper attempts to resolve this gap in the literature by introducing a post-vocalic obstruent emergence (POE) as a recurring sound change with a phonetic (aerodynamic) basis. Possible cases are identified in Tibeto-Burman, Austronesian, and Grassfields Bantu. Special attention is given to a novel case in the Tibeto-Burman language Huishu.
