Equipment making it possible to pick up and transmit distantly the speech of a person positioned in a disturbed medium so as to carry out a processing of this speech. It includes an actual antenna 1 fixed with respect to the person and which focuses the latter's mouth whilst rejecting external waves, and conditioning electronics 6 yielding an analogue output quantity representing the acoustic pressure information P or 1 linear combination of the particle pressure and particle speed P + rho CV which is representative of the acoustic waves emanating from the speaker, rho being the density of the air and C the speed of propagation of the waves. <IMAGE>
