As midsagittal profiles constitute a privileged interface between motor control and acoustics in speech production, Bergame, an articulatory-acoustic model, has been developed at ICP. It is constituted of: (1) a physiologically-oriented articulatory model, elaborated by statistical analysis from cineradiographic data acquired on a reference subject; (2) a model of midsagittal-to-area function conversion based on the same subject. The study shows a good ability of the model to reproduce the original data at all three articulatory, geometric and acoustic levels.
