We study the ability of sub aquatic divers to communicate by speech by means of an air regulator mouthpiece equipped with an acoustical sensor. These specific constraints on elocution led us to carry out an aerodynamic study to check phonation, an EPG study to observe the modification of articulation, and an analysis of labial forces involved with a special mouthpiece. Tests on intelligibility enabled us to evaluate the device in situation of real diving. In the current state, the various results let foresee a reduced but real possibility of spoken communication with a mouthpiece to certain conditions.
