Speech Prosody Of French Regional Varieties

This paper compares the prosody of 6 varieties of French spoken in three different areas: France (Paris and Lyon), Belgium (Tournai and Liege), and Switzerland (Geneva and Neuch tel). The objective is to adress whether some regional varieties, namely those of Geneva and Tournai, are closer to standard French (i.e. the varieties spoken in France, represented here by Paris and Lyon) than others (Neuch tel and Liege). The recordings of the same text read by 4 speakers representing each variety were semi-automatically processed in order to study accentuation, speech rate and rhythm, and 8 prosodic measures that can possibly discriminate the 6 varieties were compared. A top-down clustering supported evidence for the expected classification with regard to the "standard" varieties, while a bottom-up clustering pointed out a more contrasted configuration.
