This paper presents an adaptive LSB (Least Significant Bit) algorithm to embed dynamic secret speech information data bits into public speech of G.711-PCM (Pulse Code Modulation) for the purpose of secure communication according to energy distribution, with high efficiency in steganography and good quality in output speech. It is superior to available classical algorithms, LSB. Experiments show that the proposed approach is capable of embedding up to 20 Kbps information data of secret speech into G.711 speech at an average embedded error rate of 10− 5. It meets the requirements of information hiding, and satisfies the secure communication speech quality constraints with an excellent speech quality and complicating speakers’ recognition.
