Title:
VOICE ENHANCEMENT DEVICE, VOICE ENHANCEMENT METHOD, AND VOICE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/105077
Kind Code:
A1
Abstract:
A voice enhancement device comprises: a first filter (21) which extracts a component including a fundamental frequency (F0) of voice from an input signal, and outputs the component as a first filter signal; a second filter (22) which extracts a component including a first formant (F1) of the voice from the input signal, and outputs the component as a second filter signal; a third filter (23) which extracts a component including a second formant (F2) of the voice from the input signal, and outputs the component as a third filter signal; a first mixing unit (31) which mixes the first filter signal and the second filter signal and outputs a first mixed signal; a second mixing unit (32) which mixes the first filter signal and the third filter signal and outputs a second mixed signal; a first delay control unit (41) which delays the first mixed signal by a first delay amount (D1) to generate a first voice signal; and a second delay control unit (42) which delays the second mixed signal by a second delay amount (D2) to generate a second voice signal.
