The aim of the work to be reported here is to attempt to verify that some dialectal varieties of a restricted area show sensible differences in their prosody and that normally the same differences characterise the prosodic system of speakers when performing sentences in Italian. To verify these hypothesis two kind of experiment were carried out: a perceptual recognition test based on sentences differing only by prosodic cues and uttered in Italian by different speakers of the region; a detailed phonetic inspection of the acoustical makeup to detect which cues are most likely to be responsible for the listener success in the recognition task.
