Abstract
The work is devoted to subband decomposition scheme and training set composition effect on quality of reconstructed speech when synthesising codebooks for multiband CELP-coders. Codebooks quality and its dependence on the codebooks structure are studied. The research work presents multiband codebook with multistage organization and reconfigurable structure optimized by SNR, Bark Spectrum Distortion (BSD), Modified Bark Spectrum Distortion (MBSD) and Noise-to-Mask Ratio (NMR) criteria for control by psychoacoustic model on the base of Warped Discrete-Fourier Transform (WDFT).
