SOUND QUALITY ADAPTION DEVICE

摘要

PURPOSE:To attain high quality editing synthesis by converting to a spectrum parameter of a reference sound in an optimum section decided based on a decision result of a distance value between an adaptive input sound and the reference sound. CONSTITUTION:A distance value calculation means 14 calculates and outputs a spectrum parameter distance value 15 such as spectrum strain by correspondence between frames by e.g. DP matching between a partial reference sound spectrum parameter 12 and a partial adaptive input sound spectrum parameter 13. An optimum section decision means 16 inputs the spectrum parameter distance value 15, and detects an optimum reference sound section to output it as an optimum reference sound partial section 17. Then, a conversion means 18 converts the partial adaptive input sound spectrum parameter 13 into the partial reference sound spectrum parameter 12 of the optimum reference sound partial section 17 with frame correspondence by the DP matching to output it as a conversion sound spectrum parameter 19.
