An adaptive to acoustic interference algorithm for coding speech signals based on CELP codec for V.A. Kotelnikov and Khurgin-Yakovlev representation has been developed and studied. The aim is to develop and study the algorithm for adapting CELP codec to the effects of acoustic interference. This is achieved by choosing separate sets of CELP codec parameters, which, when exposed to various types of acoustic interference, provide higher quality of reconstructed speech at codec output.
Key words: speech signal, acoustic interference, adaptive codec, CELP, primary coding, speech quality.
