PRESLA: An original device to measure the mechanical interaction between tongue and teeth or palate during speech production

An original experimental procedure is presented to measure the mechanical interaction between tongue and teeth and palate during speech production. It consists in using edentulous people as subjects and to insert pressure sensors in the structure of a replication of their dental prosthesis. This is assumed to induce no speech production perturbation for subjects who are used to speak with their prosthesis. Data collected from 4 subjects of French demonstrate the usability of the system.
