In applications like VoIP, speech codecs have to deal with excessive packet losses, caused by network errors and/or delays. In this paper, a new method for the reconstruction of lost speech spectral envelopes is presented, which is based on a statistical estimation function. We suggest the usage of a minimal "corrective" bitstream and propose coding with side information (CSI) techniques for an efficient forward error correction (FEC) strategy. The proposed methods are tested on multiple… CONTINUE READING
