DEVICE AND METHOD FOR DATA PROCESSING, DEVICE AND METHOD FOR LEARNING AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To obtain high quality synthesized sound. SOLUTION: In a signal receiving section 94 of a CELP (Code Excited Linear Prediction Coding) system portable telephone, the code outputted by a channel decoder 21 are decoded into decoded residual signals and decoded linear prediction coefficients. In a predicting section 106, predicted values of true residual signals are obtained by employing the decoded residual signals and tap coefficients obtained by learning. Then, in a voice synthesis filter 29, voice synthesis is conducted by using the residual signals and linear predicted coefficients respectively obtained by the sections 106 and 107.
