The present invention relates to a communication apparatus for handicapped people. This apparatus is characterised in that it is fitted with a device for simulating a key stroke which is constituted by an interface card which comprises two or more analog multiplexers Mx1, Mx2, in particular of the CMOS type, associated with the rows ax, bx, cx, dx, ex and with the columns 0 to 9 of the keyboard matrix, so that the cross connections which they allow to be established simulate mechanical pressure on one key of the keyboard, the outputs of the two analog switches Mx1 and Mx2 being directly connected together or via an appropriate capacitance. Application to people with motor and/or cerebral handicaps. <IMAGE>
