title: Determination of velum opening for French nasal vowels by magnetic resonance imaging.
abstract: MRI techniques have been used to describe velum opening of French vowels. Data based on 18 joined axial slices of 4 mm thickness were recorded with four subjects. Differences in velum opening are calculated from areas measured in the tract between the lowered velum and the back pharynx wall. Results show that for all subjects, the back vowel [symbol: see text] has the smallest opening, while some variations are observed for the other vowels.
