An electronic telephone directory-dialer module which makes it possible for a user to automatically dial any party listed in the directory by using a dial tone telephone set for this purpose, without having to manually dial the telephone number code on the keyboard of this set. Included in the module is a data base and a keyboard by which one enters into the base the names, addresses and telephone number codes of all parties of interest to users of the directory. Operatively coupled to the electronic directory is a dialer constituted by a tone generator adapted to convert the telephone number code of any selected party into corresponding dial tones and to reproduce those tones in a loud speaker. The base of the telephone set is provided with a slot for receiving the module, the slot incorporating a microphone which registers with the loud speaker of the socketed module and is coupled to the telephone line. In this way, dial tones emitted by the speaker and picked up by the microphone are conveyed over the telephone line to automatically dial the selected party.
