The book investigates historical patterns of vowel diphthongization, assimilation and dissimilation induced by consonants – mostly (alveolo)palatals – in Romance. Compiling data from dialectal descriptions, old documentary sources and experimental phonetic studies, it explains why certain vowels undergo raising assimilation before (alveolo)palatal consonants more than others. It also suggests that in French, Francoprovençal, Occitan, Rhaetoromance and dialects from northern Italy, mid low vowel diphthongization before (alveolo)palatal consonants started out with the formation of non-canonical falling diphthongs through off-glide insertion, from which rising diphthongs could emerge at a later date (e.g., Upper Engadinian OCTO ‘eight’ > [ɔc] > [ɔ(ə̯)c] > [wac]). Both diphthongal types, rather than canonical falling diphthongs with a palatal off-glide, could also give rise to high vowels (dialectal French [li]

The book analyzes the articulatory motivation of several adaptation processes (place assimilations, blending, coarticulation) involving consecutive consonants in heterosyllabic consonant sequences within the framework of the degree of articulatory constraint model of coarticulation. It also shows that the homorganic relationship between two heterosyllabic consonants contributes to the implementation of manner assimilations, while heterorganicity as well as sonorancy and voicing in the syllable-onset C2 are key factors in the weakening of the syllable-coda C1. Experimental and descriptive evidence is provided with production, phonological and sound change data from several languages, and more especifically with tongue-to-palate contact and lingual configuration data for Catalan consonant sequences. The book also reviews critically research on the c-center effect in tautosyllabic consonant sequences which has been carried out during the last thirty years.
