Speech Watermarking Using Discrete Wavelet Transform , Discrete Cosine Transform and Singular Value Decomposition

The main goal of this paper is to embed a watermark in the speech signal, using the three techniques such as Discrete Cosine Transform (DCT) along with Singular Value Decomposition (SVD) and Discrete Wavelet Transform (DWT).In this paper, various combinations were tried for embedding the watermark image into the audio signal such as DWT and SVD, DCT with… CONTINUE READING
