摘      要：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.
