Tonally conditioned vowel raising in Shuijingping Mang

Abstract

In the Mang (Hmongic) dialect of Shuijingping, Guizhou, China, vowels are raised in certain tonal contexts. When a syllable bearing the historical A2 tone occurs in sandhi context, it surfaces with a low tone (historical S) and a raised vowel nucleus. When a syllable bearing the C2 tone occurs out of sandhi context, it also surfaces with a raised vowel. In most other documented cases of tone–vowel quality interactions, there is some factor, such as syllable structure, metrical structure, or vowel duration that mediates between tone and vowel quality. These earlier analyses cannot be straightforwardly extended to Shuijingping Mang since no synchronic mediating factor seems to be present. However, this paper shows that, historically, there was another mediating factor between tone and vowel quality, namely voice quality. It is common for tones in East and Southeast Asian languages to have characteristic phonation types. It is also common for phonation type to affect vowel quality. Comparative evidence shows that the tones that condition the vowel alternation in the present-day language historically underwent a tonally-driven breathy-modal voice alternation. Subsequently, the tonal grammar has changed; however, vowel raising remains as a synchronic alternation.
