Abstract
本文研究布農語東埔方言的音韻結構。作者以自主音段的音韻學理論描述 分析布農語東埔方言的音韻現象。本文共分為五章。第一章簡介布農語在 南島語族的歸屬、東埔方言所屬南部方言在台的分布、南部方言音韻上不 同其它方言之處。其次簡單的回顧了以往學者對布農語所作的貢獻、本文 的寫作動機及間架、方言調查點其發音人的年籍資料和調查時間及分析材 料所據。在第二章中，作者運用不同以往學者的空區徵性理論(Feature Geometry)描述了東埔方言的輔音、元音分布所產生的同化、加插等現象 。第三章處理較音段為高的音韻單位：音節。本章描述了東埔方言的音節 結構 (syllable-structure)、音節組成(syllabification)及構詞變化所 可能帶來的音節重整(resyllabification)。章節末了則概括的交代了東 埔方言的重音、它不同其它筆者所知台灣南島語言之處以及單音節實詞元 音拉長的潛在原理。第四章著重音韻變化(phonological process)。本章 描寫的音韻變化過程包括：同化(assimilation)、減音 (deletion)、增 音(insertion)及換位(metathesis)。本章主要論述參照焦點標誌( referential-focus-marker)的音韻底層可能只是個 s-而非表層的'is-。 此一論述有其歷史意義。元音換位的分析，筆者發現此一音韻變受非受音 韻條件制約。作者發現構詞運作的程序 (affix-ordering)可以解釋換位 現象乃與詞綴距離詞根(幹)遠近有關；同一運作層次的=in以及=ang應是 依附詞(enclitics)而不是詞綴(affixes)。第五章則作了個簡單的結論， 提示了作者分析未竟周詳及對布農語各方言研究的迫切。 This thesis aims at a process-based study of the phonological structure of a Bunun dialect --- Isbukun. It is divided into 5 chapters. In the introduction, we give brief accounts on the language under investigation including: its affinity with other dialects that constitute the Bunun language, its geographical distribution on Taiwan, the site where data were elicited, information of informants etc. In chapter that follows, we give analysis on Isbukun phonemes based on constriction-based model of feature geometry enunciated by Clements and Hume (1995). In chapter three, syllable is analyzed. The template CVX is proposed for Isbukun syllable structure. Brief description of stress and intonation is given after syllabification and resyllabification have been made clear. Also included is the minimal word constraint that underlies the lengthening of vowels in content words. Chapter four deals with phonological processes such as assimilation (u- fronting and monophthongization), deletion (identical segment deletion, and a-deletion), insertion (n-insertion and speculation on ['i] insertion of referential focus marker 'is-) and metathesis. The analysis of s- for Isbukun referential marker is diachronically significant. And the analysis of metathesis results in an affix-ordering schema that suggests the =in and =ang, which are often taken as affixes by Bunun students, are best regarded as enclitics. The thesis is then concluded by calling for studies to document the endangered (probably doomed) language.
