  • Abstract
    A zero-watermarking method based on vector quantisation (VQ) of linear prediction coefficients (LPCs) is proposed. The characteristic of natural speech that the VQ indices of LPCs among neighbouring frames tend to be very similar is utilised to generate the secret key. Simulation results demonstrate excellent imperceptibility and robustness of our algorithm.
