Abstract
A synthesis filtersynthesizes a plurality of wide-band speech signals by combining wide-band phoneme signals and sound source signals from a speech signal code book, and a distortion evaluation unitselects one of the wide-band speech signals with a minimum waveform distortion with respect to an up-sampled narrow-band speech signal output from a sampling conversion unit. A first bandpass filterextracts a frequency component outside a narrow-band of the wide-band speech signal and a band synthesis unitcombines it with the up-sampled narrow-band speech signal.
