Abstract
The adaptive multi-rate - wideband (AMR-WB) speech coding standard will improve the speech quality of telecommunication applications compared to the traditional narrowband speech transmission. This work presents a performance evaluation of the different modes of the AMR-WB standard for hands-free car kits. These investigations consider different noise situations, single and multichannel noise reductions systems, and the possible Bluetooth link between the hands-free device and the mobile phone.
