CONSTRUCTING OF PSEUDOINVARIANTS AND DIGITAL WATERMARKING OF SPEECH SIGNALS BASED ON A SINGULAR VALUE DECOMPOSITION

Dmytro Dmytrovych Peleshko Yuriy Myronovych Pelekh, Ivan Viktorovych Izonin

Presented digital watermarking method of speech signals based on a constructing of quasistationary intervals, pseudoinvariants and singular value decomposition. Proposed a solution to the problem of building quasistationary intervals of speech signal. This method is based on the characteristics of singular value decomposition of square matrices of operators defined on the elementary intervals. Feature of these methods is their independence from the model voice tract. Watermarking method not dependent on input signal and watermark itself.
