提出了一种基于小波变换和BCH编码的语音水印算法。该算法的特点是：1）采用更稳定的嵌入编码策略，更有效地抵抗压缩攻击：2）利用小波变换的多分辨率特性和BCH纠错码提高水印的鲁棒性; 3）根据人眼感知的临界频带，采用自适应算法将水印嵌入到低频、中频或高频分量中; 4）该方案不需要原始语音信号就能提取水印。实验结果表明，该算法是不可闻的和鲁棒性对G.711，G.726，和GSM 6.10语音编码标准。
This paper proposes a novel speech watermarking algorithm using wavelet transform and BCH coding. The characteristics of the proposed algorithm are as follows: 1) a more steady embedded code strategy adopts to resist the compressed attack more effectively; 2) the uses of multi-resolution property of wavelet transform and the BCH error correcting code to improve the robust of watermark; 3) the watermark will be embedded into the low-, middle-, or high- frequency components by adaptive algorithm according to human perceptual critical bands; 4) the proposed scheme can extract the watermark without using the original speech signal. Experimental results show that the proposed watermarking algorithm is inaudible and robust against G.711, G.726, and GSM 6.10 speech coding standards.
