VOICE EXTENSION DEVICE, VOICE CONTRACTION DEVICE, VOICE EXTENSION METHOD, VOICE CONTRACTION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce degradation of voice quality by voice extension and contraction processing.;SOLUTION: A voice processing device 1101 extends and contracts a voice signal with magnification instructed via an input device 1111. Extension and contraction are applied for each predetermined unit waveform. A control section 1121 puts a priority order for performing insertion of a new unit waveform or replacing to the new unit waveform, for each predetermined unit waveform, and according to the order, the insertion or the replacing is performed, and thereby, the voice signal is gradually extended and contracted. The new unit waveform is created based on an original unit waveform, however the same unit waveform is not made continuous so that the voice after extension and contraction processing may not become unnatural.;COPYRIGHT: (C)2008,JPO&INPIT
