This system exploits the advancements in speech processing to hide efficiently secret speech in narrowband cover speech. Linear predictive coding is used to represent the secret speech with reduced number of parameters. These parameters are embedded in selective perceptually-irrelevant frequency locations of the cover speech. Objective and subjective measures show that the resulting stego speech, which contains the secret message, is indistinguishable from the cover speech. © Springer-Verlag Berlin Heidelberg 2012.enLicense to reuse abstract has been provided by Springer Nature and Copyright Clearance Center.Data hidingLinear Predictive CodingNarrow bandsObjective and subjective measuresSecret messagesSpeech processingSteganographyConference PaperCopyright : © Springer-Verlag Berlin Heidelberg 2012
