Information on Voice service

The GSM voice service provides toll-quality speech at a data rate of 13.2 kbps in one full-rate traffic channel. The difference between the usable data rate and the raw channel data rate is used for carrying parity bits for the GSM channel coding.
     While the quality of the GSM voice service is noticeably lower than that provided by an ISDN telephone connection in the fixed network, it is still usually judged sufficient to allow speaker recognition.
