A modification of the Khurgin – Yakovlev representation in joint implementation of codec and masker of speech signals with the ability to protect phonograms from falsification during storage and transmission is proposed to be used. The aim of the work is to develop an algorithm for joint implementation of primary codec and masker of speech signals with the possibility of protecting phonograms from falsifications. The implementation of primary codecs of speech signals based on the modification of the Khurgin – Yakovlev representation makes it possible to increase noise immunity as well as reconstructed speech quality at the output of transmission system, or to reduce transmission rate with the same quality, to provide simpler implementation of synthesizing filters, and to realize the possibilities of parallel processing. The possibility of joint implementation based on primary codec, masking algorithms as well as an algorithm for detecting falsified phonograms and recovering falsified phonograms based on a modification of the Khurgin – Yakovlev representation is shown.
Key words: : primary codec, speech signal, speech masking, phonogram falsification detection, phonogram recovery, Khurgin – Yakovlev representation modification, reconstructed speech quality, secure transmission systems.
