The estimation of noises is very important to remove noises from voices with background noises. This paper proposed a voice detection method using a silence feature normalization and voice energy maximize. In the high signal-to-noise ratio for the proposed method was used to maximize the characteristics receive less characterized the effects of noise by the voice energy. Cepstral feature distri...

Approach: The paper reviews the literatures on employee voice and silence and then builds a conceptual framework that can be used to explain employee si...

This paper introduces SkyDe (Skype Hide), a new steganographic method that utilizes Skype encrypted packets with silence to provide the means for clandestine communication. It is possible to reuse packets that do not carry voice signals for steganographic purposes because Skype does not use any silence suppression mechanism. The method’s proof-of-concept implementation and first experimental re...
