The Research on Tibetan Compound Consonants of Propositional Nasal [n] in Xiahe Dialect by Means of Electropalatograph

Abstract

Abstract. In our study we focus on Xiahe dialect which is one of the most representative Ando dialect in Tibetan, and research the compound consonants of [nd], [ndz], [ ] and [ ]by dynamic electropalatograph, whose propositional nasal is [n]. In this paper, the frame of each compound consonant is analyzed, which is the biggest contact area of tongue and palatal of main consonant; and two parameters , contact anteriority (CA) and contact centrality(CC) are extracted. The influence of propositional nasal[n] on the main consonant is studied, comparing the differences between main consonants of compound consonants and single consonants which is the same place of articulation. From this study, we find that the position of the main consonant is affected by the propositional nasal in different degree and it is close to the direction of the preposition consonant [n].
