A sociophoentic study of intergenerational differences in Kemie language

Abstract

Previous sociophonetic studies have primarily concentrated on European languages or other dominant languages, with Chinese dialects and minority languages receiving less attention. This article aims to examine the phonetic variations of vowels, stops and tones emerged owing to age differences in Kemie Language, an Austroasiatic language in China. 18 speakers were categorized by age into young, middle-aged and older groups with 6 speakers in each group. Acoustic parameters such as formants, VOT, f0 and duration were extracted, and linear mixed effects model and repeated measures ANOVA in R were employed to test whether the above parameters were significantly different across the groups. Results show that: (1) The monophthongs /ɛ/ /a/ /ɔ/ manifest significant variations through tongue height or frontness or both. (2) VOT values of /b/ in the above three groups are significantly different and inverse with age, while no consistent conclusions can be reached in terms of /d/ /ɡ/. (3) Low-rising (13) and high-rising (35) tones with stop codas (cu yun wei) haven’t merged across the groups, but pitch range of the two tones become narrower with decreasing age; Low-rising (13) and mid-level (33) tones with sonorant codas (shu yun wei) have merged across groups.
