In this paper we propose a new scheme for blind watermarking of speech and audio signals. We used the discrete wavelet transform (DWT) after framing the signal, and then we applied the discrete cosine transform (DCT) on each frame. For correlation pu

In this paper, a robust and blind speech watermarking technique is proposed using a combined scheme based on discrete cosine transform (DCT) and discrete wavelet transform (DWT) Algorithms within signal sub-sampling. To achieve good imperceptibility,

In this work, a combination between Discrete Wavelet (DWT) and Discrete Cosine Transforms (DCT) is used to watermark a digital human speech sequence. This novel combination is tested under hard conditions of attacks and additive noise and proves its
