Two phonological processes in Paiwan are revisited: the /w/~/v/ alternation and labial dissimilation. New Paiwan data collected in the east show that the /w/~/v/ alternation only operates at word level (suffixation), not at phrasal level (encliticization). Labial dissimilation no longer applies to the stems with a labial segment in the second syllable. As for Seediq, the phonological impact on Toda regarding the sound correspondence of /g/ (Tgdaya/Paran)-/ɣ/ (Truku)-/w/ (Toda) in the three dialects is discussed. This paper proposes contrastive hierarchy for the phonological patterning of the two languages and concludes with both synchronic variations and diachronic implications.phonological patterningsegment /w/contrastive hierarchyPaiwanSeediqFormosan languages
