提出了一种基于合成分析算法的语音信息隐藏方法。该方法能够在原始语音数据中嵌入动态的语音信息数据比特，隐写效率高，输出语音质量好。它上级于经典算法，例如，最低有效位，它只能将固定1、2和4位数据分别嵌入到原始载波语音中。
An approach for speech information hiding based on the analysis by synthesis algorithm is presented. This approach can embed dynamic secret speech information data bits into original carrier speech data, with good efficiency in steganography and good quality in output speech. It is superior to classical algorithms, e.g., least significant bit, which can only embed fixed 1, 2 and 4 bit data into original carrier speech individually.
