Research of Speech Covert Communication Technique Based on 3G AMR

摘要：

This paper presents a speech covert communication algorithm based on the 3G AMR. The secret speech is encoded by a 600bps very low bit rate speech coding algorithm, while the ordinary speech is encoded by the AMR. After that, all the binary parameters of the secret speech are embedded into the type of B or C bit streams of ordinary speech. Using this technique, the secret speech can be hidden in the ordinary speech transparently,a real-time speech covert communication system could be successfully achieved.
