Abstract(in English) | This paper presents the standardization activity in selecting a speech coding algorithm for the Digital Simultaneous Voice and Data system specified in ITU-T Recommendation V.70 that transmits voice and data simultaneously through the public telephone network with MODEM. The requirements for this system were toll speech quality, low complexity, and short delay time at low bit rate less than 12 kbit/s, and were not met by current speech coding standards. The reduced complexity CS-ACELP was selected from among 5 candidates as the coding algorithm after the subjective selection tests and was recommended as Annex A to G.729. The subjective test in Japanese shows that this Annex is compatible with G.729 and meets all the requirements. |
