Abstract

PURPOSE:To reduce erroneous calling dependent upon dial erroneous operations or improve service in the telephone set operation, by generating button information corresponding to the dial number from a sound synthesizer with sound. CONSTITUTION:When push-button dial 3 is depressed, transmitter T is disconnected by interlocking common switch 5a, and push-buttom dial oscillator 4 is connected to the telephone set line. Receiver R is disconnected by switch 5b, and electric power is supplied to the sound generating part from power source 14 by switch 5c. Push-button dial information is transferred to oscillator 4, and a signal of the corresponding frequency is transmitted from terminals 1a and 1b to the station side. Simultaneously, button information is transferred to decoder circuit 7, and sound information expressing button information with words is read from sound information memory part 10 according to the decoder result by control part 9 of sound synthesizer 8 and is synthesized to a sound signal by sound signal forming part 11, and the sound signal is subjected to power amplification to drive speaker 13. That is, button information is generated with sound.
