Abstract :
The article describes and compares the effectiveness of two steganographic methods dedicated for speech signal processing. The first method is based on the change in the drift of a phase angle (Drift Correction Modulation, DCM), whereas the second uses spectral amplitude correction (Pattern Magnitude Modulation, PMM). The results of experiments corroborating the robustness of the methods against degrading factors (AWGN, frequency drift, radio channel VHF) were presented. The results of signal fidelity tests using ITU-R BS116-1 were also described.
