本文提出了一种基于清音音调延迟的AMR自适应隐写方案（PDU-AAS）。现有的基于基音延迟的AMR隐写方案破坏了有声语音片段的基音延迟的短时相对稳定性，并且更容易被现有的隐写方案检测到。特别是，详细分析了AMR浊音和清音语音段的基音延迟分布，基于AMR清音语音基音延迟序列不具有短期相对稳定性的特点，提出了一种AMR自适应隐写方案，该方案根据相邻基音延迟的分布特征自适应地选择清音段中的嵌入位置，通过修改基音延迟来嵌入秘密信息，同时不破坏基音的短时稳定性。延迟。实验结果表明，该方案具有良好的隐蔽性和隐藏能力。最重要的是，对比实验结果表明，该方案具有良好的安全性，能够抵抗现有隐写分析算法的检测。该方案的原理可以应用于其他基于语音编解码器的基音延迟的隐写方案，例如G723.1、G.729。
In this paper, a novel AMR adaptive steganographic scheme based on pitch delay of unvoiced speech (PDU-AAS) was proposed. The existing AMR steganographic schemes based on pitch delay destroy the short-time relative stability of pitch delay of voiced speech segments and they are easier to be detected by the existing steganographic schemes. Especially, the pitch delay distribution of AMR voiced and unvoiced speech segments are analyzed in detail, and based on this characteristic that the pitch delay sequence of AMR unvoiced speech do not have short-term relative stability, we proposed an AMR adaptive steganographic scheme which selects the embedded position adaptively in the unvoiced speech segment, which is determined by the distribution characteristic of the adjacent pitch delay, and embeds the secret message by modifying the pitch delay without destroying the short-time stability of the pitch delay. The experiment results shows that the scheme has good concealment and hiding capability. Most important of all, the comparing experiment results show that the scheme has good security to resist the detection of the existing steganalysis algorithms. The principle of the scheme can be applied to the other steganographic schemes based on the pitch delay of the speech codec, such as G723.1, G.729.
