Phonological variation in OY : a comparison of four varieties
Abstract:
Oy, an understudied West Bahnaric Austroasiatic language of the southern Lao PDR, has been observed to have extensive variation (Sidwell & Jacq, 2003). The extent, precise nature and geographical distribution of this variation is unknown. In this study, nine speakers total from four Oy villages were recorded. Data for the present analysis are drawn from recordings of an 1800 item wordlist from one village, serving as a basis for 619 items representative of Oy phonotactics. This shorter wordlist was used for data collection in three more villages and phonological comparison. In the comparative study of each village, systematic variation in sound patterns was the main focus, but lexical variation was also considered. Results show that there are three distinct phoneme inventories among the four villages, and that phonetic variation does not form any further, internally consistent dialects. One village shows a significantly higher rate of unique phonological features and is more historically conservative than the other varieties. The determining factor in the differing phoneme inventories is the status of implosives and glottalized nasals; two villages contrast them, while they are in free variation in a third village, and in the fourth village no implosives but only glottalized nasals are present. Other dialectal differences include patterns of monophthong and diphthong contrast vs. monophthongs or diphthongs only, preservation of vowel length contrast, morphophonological processes concerning prefixation and infixation, and sesquisyllabification triggered by historical cluster onsets ?r, hr.
