Abstract

New wideband speech coding standards like the AMR-WB and the ITU G.729.1 codecs will improve the speech quality of telecommunication applications in the near future. To provide the same speech quality with hands-free devices that have a Bluetooth link, a bandwidth extension for the speech transmission with Bluetooth is required. This work presents a low complexity and low latency speech coding scheme that is backward compatible to the current Bluetooth standard and can be implemented with off-the-shelf Bluetooth chips.
