Real Steganography in Non Voice Part of the Speech
Embedding a secret message into a cover media without attracting any attention is known as steganography. Steganography is one of the methods used for hidden communication purposes. One of the cover media that can be used for steganography is speech. All the methods that the authors have found for audio steganography, changes the values of maximum number of samples from the audio signal. Usually change the sample values of the signal annoying the listener and reduce perceptual transparency. So the special methods are required for hiding the information in audio signal. In this paper, they propose a new steganographic method in speech signals. In this method, secret data are hidden in the silence part of the speech signal.
