Abstract
In this work we introduced an efficient method to hiding speech signal that encoding with LPC (linear predictive coding), these parameters converted to LSF (line spectral frequency),these were less sensitive to change and more robustness. These parameters embedded in cover speech after converting in wavelet domain that split high frequency from low frequency. The high frequency converted to frequency domain by Fast Fourier Transform by replacing the magnitudes with these parameters. The phases kept and inverse Fast Fourier Transform to obtainwavelet domain and obtained the stego speech that perceptually indistinguishable from the equivalent cover speech.The proposed method allows hiding a large amount of secret information while rendering the steganalysis more complex.
