FIELD: telephone communications. SUBSTANCE: telephone set has vocoder that functions to compress voice signal arriving from telephone transmitter into output burst data and corresponding token data. Voice identifying device separates token data from vocoder output burst data and compares these token data with token data recorded in nonvolatile memory to detect token data similar to input token data and difference between them so as to find out if input voice signal has been adequately identified considering this difference. EFFECT: provision for integral capabilities of voice identification. 13 cl, 4 dwg
