摘要
文章提出了一种基于小波变换的语音伪装算法。它把秘密语音嵌入到数字音频信号中实现保密通信。实验表明该算法的隐蔽性好,隐藏的数据量大。
This paper present a novel kind of voice camouflage algorithm based on wavelet transform. It embeds a secret voice into a digital audio signal in order to communicate secretly. The experimental results show that the algorithm can hide high capacity of date imperceptibly and it is robust to routine operations on digital audio signal.
