摘要 研究流媒体通信中G.723.1高速率语音编码器的分级隐藏方法,分析线谱对频率(LSF)参数的隐藏性能,给出一种基于临界带宽的LSF参数隐藏性能分析方法。在此基础上,结合数位信息法,提出一种G.723.1高速率语音流的信息隐藏算法。实验结果证明了该算法的有效性。 This paper studies the hiding method of the G.723.1 high-rate speech coder which is used in streaming media communications,analyzes the hiding performance of Line Spectrum Frequency(LSF) parameters,then proposes the LSF parameters hiding performance analysis method based on critical bandwidth.By using the method of digital-position information,it proposes the information hiding algorithm of G.723.1 high-rate speech flow.Experimental results proves the validity of the proposed algorithm.
