Developments in the Romance-speaking area provide an extremely useful testing ground for phonetic hypotheses regarding sound change. Detailed investigation of nasalisation-related sound changes (e.g. an > ãn > ã) in the Romance dialects of Northern Italy has uncovered a range of pervasive suprasegmental effects. In the long tradition of research on the development of distinctive nasalisation, attempts at phonetic explanation have focussed largely on articulatory causation. However, most recent evidence suggests that many of the sound changes observed in Northern Italy and elsewhere have a substantial perceptual basis.
