Abstract :
The CCITT (International Telegraph and Telephone Consultative Committee) Study Group XV is in charge of studies on speech processing. SGXV has already drafted standard G.728 for a 16-kbit/s low-delay speech coding algorithm and is now studying 8-kbit/s speech coding algorithms. The paper reviews the recent activities of SGXV/WP2 on 8-kbit/s speech coding algorithm. These activities include discussion of the algorithm´s application, of performance requirements and objectives, and of the procedure for evaluating the candidate algorithms. It also introduces one of the probable algorithms and presents this working group´s plans for future work
