藏语机读音标SAMPA_ST的设计

摘要

该文选取具有代表意义的藏语卫藏方言的拉萨话、安多方言的夏河话以及康方言的德格话进行语言调查；整理归纳藏语三大方言音系,包括单辅音、复辅音、单元音、复合元音和辅音韵尾,以及三大方言声调；依照SAMPA的规则建立适合于藏语三大方言的机读音标,并设计了SAMPA_ST的自动标注系统,实现文音转换功能,为语音的韵律特征分析和语音工程的研究提供依据.%This paper investigates three representative dialects in three main dialect branches as subjects for language investigations: Tibetan Lhasa dialect of Tibet branch, Xiahe dialect of Ando branch and Dege dialect of Kang branch. It summarizes their three dialects' phonetic systems, including single consonants, compound consonants, monophthongs, compound vowels and consonant-tails, as well as their tones. In accordance with SAMPA rules, it establishes the machine reading IPA suitable with these Tibetan three dialects and designs SAMPA_ST automatic labeling system to realize the text-speech conversion. It provides necessary data for the research on speech prosodic feature analysis and speech projects.
