Ste gano graphic systems are used for the transmission of hidden data in the original signal. The article describes the algorithm of the hidden data transmission using the speech signal as a carrier. The echo method is used for data embedding. In order to improve the decoding efficiency of embedded data, the procedure of voicing correction and mechanism of informed coding were developed and implemented. We checked the robustness of proposed steganographic system against the transmission of speech signal through VoIP, robustness against to steganoanalysis as well as the perception transparency of the embedded information in the original (host) signal.
