Abstract

PURPOSE:To obtain a telephone system which enables to transmit/receive a call even for a person handicapped in hearing or speaking by converting a call receiving signal from a telephone set to a character, displaying it, transmitting the character signal instead of an answering voice, and displaying the character at the party of speaking. CONSTITUTION:The call receiving signal of the voice from a telephone set 1 is inputted to a voice analysis part 7 and analyzed by feature extraction, and the analyzed data is compared with a data from a voice recognition data memory part 9 through an identification part 10. Then, the voice recognized as coincidence is identified by the identification part 10, and a character data corresponding to the identified voice is read out from a character data memory part 11, generated to the character signal through a character signal generation part 12 and displayed at a display part 13. Instead of the answering voice, the data of the character inputted by operating a character data input part 14 is converted to the required signal by a character code conversion part 15, transmitted through a telephone line 3, converted to a signal for display by a character signal conversion part 4 at the calling destination, inputted to a display part 5 and displayed.
