A la recherche des temps perdus : Variations sur le rythme en français (Regional Variations of Speech Rhythm in French: In Search of Lost Times) [in French]

______________________________________________________ Regional Variations of Speech Rhythm in French: In Search of Lost Times This paper addresses the relevance of speech rhythm acoustic measures for the description of some standard, regional and contact varieties of French. First, the limitation of conventional speech rhythm measures (e.g. %V, ∆C or PVI) for the description of French regional variations is pointed out. Then, alternative acoustic measures of speech rhythm, based on supra-segmental characteristics associated with timing (regularity of accentual phrases) and tempo (articulation rate, speech rate) are introduced and discussed. A comparison with the conventional measures indicates that long-term measures lead to a classification which is more consistent with the expected classification, either for the description of continuous similarities or categorical grouping.
