This paper proposes a kind of information hiding method which is based on dynamic codebook generating technique,together with the corresponding inserting method and extracting algorithm. This method greatly solves the problem of deficiency in anti-testing of code analysis,which is faced by the information hiding that is based on static codebook partition techniques. The experimental result shows that the proposed algorithm can get 450 bps steganographic capacities within13. 3 Kbps carrier rate,while the loss of PESQ value of speech with steganographic information is less than 6%.
