Abstract：

This　paper　describes　a　8-32　kb/s　embedded　speech　codec　submitted　as　a　candidate　for　the　ITU-T　Embedded　Variable　Bit　Rate　(EV-VBR)　standardization.　The　coder　is　built　upon　a　2-stage　coding　structure　consisting　of　embedded　ACELP　coding　from　8　to　16kb/s　and　embedded　TCX　coding　at　24　and　32　kb/s.　The　coder　is　designed　to　support　bandwidth　scalability　(narrow　band　and　wide　band　signal)　and　bit-rate　scalability　(8∼32　kb/s).　The　output　bit-stream　produced　by　the　coder　is　scalable,　consisting　of　core　layer　and　four　enhancement　layers　at　8　kb/s,　12　kb/s,　16　kb/s,　24　kb/s　and　32　kb/s　individually.　ITU-T＇s　test　results　showed　that　this　coder　has　good　performance　compared　with　reference　codec.　Copyright　©　2008　ISCA.
