摘要

A flexible framework is presented which performs multipledescriptionrncoding of speech signals with two or morernchannels. The use of forward error correction codes togetherrnwith a layered speech codec permits encoding intornmore than two descriptions without excessive increase inrncomplexity. Results of a formal MOS listening test revealrnconsiderable improvements in robustness as long as basernlayer quality and the number of descriptions are chosen appropriately.rnA modification of the original encoding schemernallows trading off bit rate savings against robustness tornextreme channel conditions. Different coding schemes canrneasily be compared using a real-time demonstrator software.
