Information hiding with a cover object is referred as steganography. Here the cover object might be an image, video or speech. Speech steganography is a process of hiding the message data into a cover speech without degrading the quality of cover speech. This article has introduced a spread spectrum representation-based speech steganography using decimated wavelet transform (DWT), which decomposes the cover speech signal into approximated and detail coefficients i.e., low frequency and high frequency. Our proposed speech steganography provides enhanced imperceptibility since DWT reconstructs the decomposed information without degrading the quality of speech. Our proposed approach is an extended version of existing Fast fourier transform (FFT) based steganography, where there is a lack of imperceptibility. Simulation results proved that the proposed algorithm is superior to the conventional algorithms. Also performed good enough simulations with low bit error rate and excellent imperceptibility.
