Peculiarities of use of speech acoustic environment while embedding into it of hidden message codes

Korostil Y., Afanasyeva O.

The problems of embedding of message codes into Acoustic environment of speech are researched. The peculiarities of speech perception by human hearing are analyzed. As an example of acoustic Messager environment and codes of hidden messages embedded into it is reviewed a channel of mobile Communications in the part of transformations which are implemented with acoustic signals. Approach to build a model of process of transmission of speech via non-linear channel basing on imagination about speech signals spectrum is developed. The proposals on methods of use of such models for analysis and interpretation of distortions of signals made by transformations, implemented in example channel are presented.
