    • The present invention relates to a data processing apparatus capable of obtaining high-quality sound, etc. A tap generation section 121 generate a prediction tap from synthesized speech data for 40 samples in a subframe of subject data of interest within the synthesized speech data such that speech coded data coded by a CELP method, and synthesized speech data in which a position in the past from a subject subframe by a lag indicated by an L code located in that subject subframe is a starting point. Then, a prediction section 125 decodes high-quality sound data by performing a predetermined prediction computation by using the prediction tap and a tap coefficient stored in a coefficient memory 124. The present invention can be applied to mobile phones for transmitting and receiving speech.

    • The present invention relates to a transceiver which provides a high-quality decoded voice. A mobile telephone 1011 encodes voice data, and outputs the encoded voice data. Furthermore, the mobile telephone 1011 learns quality-enhancement data which improves the quality of a voice output from a mobile telephone 1012, based on voice data used in past learning and newly input voice data, thereby transmitting the encoded voice data and quality-enhancement data. The mobile telephone 1012 receives the encoded voice data transmitted from the mobile telephone 1011, and selects quality-enhancement data correspondingly associated with a telephone number of the mobile telephone 1011. The mobile telephone 1012 decodes the received encoded voice data based on the selected quality-enhancement data. The present invention is applied to a mobile telephone that transmits and receives voices.
