Post-Nasal Devoicing as a Sound Change
1.1. Post-nasal voicing (T > D / N ) is well attested and phonetically well motivated, both as a synchronic process and as a sound change. Locke (1983) identifies 15 of 197 languages with synchronic post-nasal voicing (PNV).1 Voicing of stops in post-nasal position is phonetically well motivated: it is the result of a combination of nasal leak and “compression” by the velum (Hayes and Stivers 2...
متن کاملPost-nasal Devoicing in Tswana
Tswana is traditionally described as having a process of post-nasal stop devoicing (/mba/ → [mpa]).

متن کاملPost-Nasal Devoicing and a Probabilistic Model of Phonological Typology
This paper addresses one of the most contested issues in phonology: the derivation of phonological typology. I argue that the unnatural process of postnasal devoicing does not derive from a single unnatural sound change, but rather from a combination of two or three sounds changes, each of which is natural and well-motivated. Evidence from both historical and dialectal data is brought to bear t...
