This project focuses on the intonational differences between diatopically closely related varieties. The case study is represented by the intonation of Salerno Italian, which will be compared with two neighboring varieties, Neapolitan Italian and Cilentan Italian. Salerno occupies a geographic position halfway between Naples, which is located north, and Cilento, which is located south. The empirical focus of the study is to compare the tunes of questions and statements in Salerno, Neapolitan and Cilentan Italian exploring the prosodic elements that contribute to the difference (or to the similarity) between these varieties. The project combines the analysis of spontaneous material (task-oriented dialogues) and controlled speech from reading tasks and from controlled experiments.
