US 6,636,586 B1 · Telephone set device capable of vocalizing a telephone number being called

Abstract

A telephone set device capable of vocalizing a telephone number being called. A line interface circuit serves as an interface between the tip and ring wires of a standard telephone circuit and the internal circuit. A ring detector detects whether a ring signal is being input. A controller provides the input of signals from the line interface circuit, the keypad, and the ring detector. A hybrid circuit divides the connecting terminals of the line interface into a voice input and a voice output. A keypad inputs the control signal or the number signal to the controller, and sets the address data in the internal memory of the controller to output the voice data. A DTMF generator generates DTMF signals to represent each key on the keypad. A number voice generator receives the address data and decompresses the corresponding compressed voice data retrieved from the internal memory. A handset receives/transmits a voice signal. A switch device cuts off the voice signal from the handset under the control of the DTMF generator when the DTMF generator outputs the DTMF signals. A speaker connected to the number voice generator, vocalizes the decompressed voice signal.

Dependent claims

A telephone set device capable of reciting a telephone number being called, comprising:

a line interface circuit for acting as an interface between a tip and ring wires of a standard telephone circuit, and an internal circuit;
a ring detector for detecting whether a ring signal is being input, and outputting a detection signal when the ring signal is detected;
a keypad for presetting a telephone number associated with the telephone set on which the keypad is disposed by providing number signals corresponding to the telephone number and control signals, the presetting being done by using a plurality of number keys and specific keys;
a controller for:
(a) receiving the number signals and control signals from the keypad when presetting the telephone number associated with the telephone set;
(b) generating information data corresponding to the number signals and control signals;
(c) storing the information data in an internal memory;
and
(d) transmitting the information data when receiving the detection signal;
a number voice generator for receiving the information data, and decompressing the information data for generation of voice signals corresponding to the telephone numbers being called;
and
a speaker, connected to the number voice generator, for reciting the decompressed voice signals before the telephone set goes off-hook.
