[en] This paper aims at describing the production of nasal vowels by 5 speakers of Canadian French (Montreal). The data consist in images of the tongue that have been tracked by ultra-sound while simultaneously recording nasal airflow with PcQuirer and the movements of the lips using a video camera. Results show that: (i) nasalization is delayed in Canadian French nasal vowels (especially /??/); (ii) the majority of the vowels are diphtongized, diphtongization being larger in front vowels than in back vowels and in closed syllables than in open syllables. The way Canadian French deals with the constraints acting upon nasalization are discussed, especially in comparison with European French.
