DEVICE AND METHOD FOR TIME/PITCH CONVERSION

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for time/pitch conversion which can easily vary the pitch and reproduction time of a reproduced voice without bringing large-sized constitution nor complexity of processing nor spoiling reproduced sound quality. SOLUTION: After the spectrum of voice data compressed as frequency data is shifted, the data are interpolated and thinned out and reconverted into voice data of time-series data.
