A phone keypad device (10) useful in enunciating sounds, which correspond to designations associated with phone keys (40), the phone keys (40) being actuatable for dialing a corresponding number or function. The device (10) includes a pad (12) with a plurality of depressible overlay portions (22) aligned with the phone keys (40) beneath, a sound chip (30), and a printed circuit (50) on the underside of the pad (12) which sends signals from the overlays (22) to the sound chip (30). When a depressible overlay portion is touched, a sound is enunciated which is indicative of the phone number or function of the phone key beneath the depressible portion. If the depressible portion is further depressed, the underlying phone key (40) actuates in response for placing a call. Alternatively, a cancellation key may be actuated to prevent automatic entry of the phone number or function previously enunciated.
