Normalized F0 values measured from a specific prosodic domain (the Accentual Phrase, AP) are used in order to compare readings from four female speakers of two varieties of French: two Canadians (Quebec City area) and two French (Vendee area). Comparisons are based on APs showing similar internal organization (contour, number of syllables, timing contour-to-text) and identical position within an utterance. Normalized F0 values show greater extra-variety variation than intra-variety for specific parts of the contours, namely the L tones of LLH continuation contour and the first L and H tones of LHL final contour. Perceptual experiments will be later conducted based on these findings.
