Title:
VOICE PROCESSING METHOD, VOICE PROCESSING DEVICE, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/172397
Kind Code:
A1
Abstract:
A voice processing device that comprises a synthesis processing part that: by synthesizing a first spectral envelope general shape for a first audio signal that represents a singing voice, a first difference that is the difference between the first spectral envelope general shape and a first standard spectral envelope general shape for a first point in time from the first audio signal, and a second difference that is the difference between a second spectral envelope general shape for a second audio signal that represents a reference voice and a second standard spectral envelope general shape for a second point in time from the second audio signal, generates a synthesized spectral envelope general shape for a third audio signal that represents transformed audio that has been produced by transforming the singing voice in accordance with the reference voice; and generates the third audio signal to correspond to the synthesized spectral envelope general shape.
