Abstract
A stand alone Personal Electronic Telephone Directory (PETD) apparatus is provided, that includes an internal telephone line segment, an off hook circuit, a Dual Tone Multi-Frequency (DTMF) receiver, a ring detection circuit, a micro-controller, a memory, a speech synthesizer, and a DTMF generator. The PETD apparatus is a stand alone device intended for connection to an individual user's home telephone line, and for access by using a common touch tone ('DTMF') telephone. The user can access the memory of the PETD apparatus of the present invention locally or remotely. Then the user can issue coded instructions by simply pressing the keys of the DTMF telephone. By giving specific instructions, the user is allowed to add, retrieve or delete data from the memory of the PETD apparatus. The PETD apparatus communicates with the user by voice, generated by the speech synthesizer. Additionally, if the PETD apparatus is being accessed locally, then the user can instruct it to dial automatically the telephone number retrieved from the memory, so that the user can continue automatically with a telephone call to the retrieved telephone number.
