本文檢視郡社布農語語料，以釐清是否有相關音韻現象提供了對於韻核前滑音在音節內部歸屬的證據。文中指出，韻核前滑音在結構上屬聲或屬韻並不能由與音節首輔音的組合型態得知，但是此語言的重音規則顯示韻核前滑音應帶音拍，因此在結構上應與韻核較為接近。此一分析間接表示布農語雖然在元音前可以有輔音後接滑音的音串、元音後允許滑音與輔音的組合，但實際上聲母及韻尾均最多只容納一個音段。

This paper examines the internal evidence for the syllabic affiliation of onglides in Isbukun Bunun, a Formosan language spoken in southern Taiwan. It is shown that although the phonotactics of the onglides and the neighboring elements does not provide crucial evidence for the status of the glides, postconsonantal onglides are structurally closer to the nucleus based on their weight-carrying behavior in stress assignment. The proposed analysis implies that although Isbukun contains prevocalic consonant-glide sequences and postvocalic glide-consonant strings, complex syllable margins are in fact not tolerated in the language.
