Résumé
Orofacial clones can display speech articulation in an augmented mode, i.e. display all major speech articulators, including those usually hidden such as the tongue or the velum. Besides, a number of studies tend to show that the visual articulatory feedback provided by ElectroPalatoGraphy or ultrasound echography is useful for speech therapy. This paper describes the latest developments in acoustic-to-articulatory inversion, based on statistical models, to drive orofacial clones from speech sound. It suggests that this technology could provide a more elaborate feedback than previously available, and that it would be useful in the domain of Computer Aided Pronunciation Training.
