1. A stand alone Personal Electronic Telephone Directory ("PETD") apparatus intended for use in combination with a telephonic device, the telephonic device being capable of automatically taking a home telephone line to an off hook state if connected to it, the stand alone PETD apparatus comprising:

  • an internal telephone line segment comprising a signal line and a common line, the internal telephone line segment having a proximate end and a caller end, the proximate end being configured so that it is capable of establishing a proximate connection of the internal telephone line segment with a proximate telephone cord connected to the telephonic device, the caller end being configured so that it is capable of establishing a caller connection of the internal telephone line segment with a line cable, the line cable being capable of connection with the home telephone line;

    an off hook circuit connected to the signal line and to the common line;

    a DTMF receiver having an input port connected to the internal telephone line segment and an output port, the DTMF receiver producing electronic signals at its output port in response to DTMF signals detected at its input port;

    a memory containing at least one name that has been stored by the user in advance and telephone number data associated with each name;

    a microcontroller connected to the off hook circuit, to the output port of the DTMF receiver, and to the memory, the microcontroller being capable of perceiving electronic signals at the output port of the DTMF receiver and interpreting the electronic signals as encoded data, the encoded data including a name request, the microcontroller being further capable of comparing the requested name to stored names and retrieving from the memory telephone number data corresponding to a stored name similar to the requested name; and

    a speech synthesizer having an output port connected to the internal telephone line segment.
