This paper investigates sound change data from the literature on the Romance languages in order to test the hypothesis that phonological processes involving adjacent segments may originate from the perceptual categorization of systematic phonetic cues. Data reveal indeed that directionality trends in phonological assimilations and insertions match those in related coarticulatory effects. Thus, it was found that vowel assimilations and glide insertions are mostly regressive if associated with consonants exerting more C-to-V anticipatory than C-to-V carryover (dark /l/) while both regressive and progressive if related to consonants favoring C-to-V anticipatory and carryover effects to a similar degree (palatals).
