Da-ang vowel length is contrastive for non-high central vowels. Although the differing in duration is accompanied by vowel quality differences,the vowel duration is the main cue for distinguishing between short and long vowels in Da-ang. © Universitat de Barcelona.Mahidol UniversityArts and HumanitiesSocial SciencesArticleSCOPUS
