Abstract
|
|
|
|
Fricated nuclei in Nuosu Yi were found to be more correctly described as fricated vowels, rather than syllabic fricativesdue to the presence of clear formant structures typical of front vowels. In this exploratory study, two types of fricated nucleiwere examined: retroflex “yr” and non-retroflex “y.” The retroflex nucleus “yr” had higher F1 and lower F3 thannon-retroflex “y”, indicating a lower tongue height. On the other hand, F2 was found to correlate not with nucleusretroflexion, but instead with onset consonant retroflexion: F2 was higher following retroflex onsets, in both vowels. Thiseffect was persistent through the entire vowel, suggesting a phonological effect, rather than a coarticulatory one. Interpretationof the F2 results require accompanying articulatory data since the usual coupling of F2 and tongue backness does not alwayshold for retroflex vowels. Examining the articulation of the fricated nuclei in Nuosu Yi is a direction for future research.
