排灣語分為南北兩個方言，在南部方言中又可分為「力里型」、「來義型」、「古樓-牡丹型」。其中的力里型方言是較為特殊且創新的音系，內部存在一些語音差異。本文系統探討力里型方言內部的六個語音變異，包括軟顎濁擦音y、小舌擦音x、齒齦塞擦音tsh、齒齦擦音s、z、邊音、齒齦濁塞音d等，並根據力里型方言的語音特點提出與之相應新的羅馬拼音方案。建議將原本根據古樓音系設計的包括dr、r、1、lj等四個符號改為力里型的r、h/q、x·/q、l。

Paiwan can be divided into two main dialects: the Northern Dialect and the Southern Dialect. The Southern Dialect includes the Raxekerek-Type, the Tjalja’avus-Type and the Kuljaljau- Sinvaudjan-Type subbranches. The Raxekerek-Type dialect is phonologically distinct and innovative, with several internal variations. This paper will discuss 6 phonological variations in Raxekerek-Type dialects, including that of velar fricative, uvular fricative, alveolar affricate, alveolar fricative, lateral and voiced alveolar stop. Based on its phonological features, it is proposed a new set of corresponding Roman transliteration, suggesting to change the original dr, r, I, lj to r, h/中, x/o, 1 in the Raxekerek-Type dialects for better matching to its phonology.
