Abstract
An apparatus and a method for restoring voice are provided. The apparatus reduces noise included in a voice signal input to a microphone and outputs a voice signal having reduced noise, detects harmonic frequencies from the voice signal having reduced noise, and restores the voice signal having reduced noise approximate to its original state before being input to the microphone according to detected harmonic frequencies of the voice signal having reduced noise.
Claims10
An apparatus for restoring an input voice signal, comprising:
- a noise reducer configured to reduce noise included in the input voice signal and outputting a voice signal having reduced noise;
- a harmonic detector configured to detect harmonics of the voice signal having reduced noise;
- and
- a harmonic restorer configured to restore the voice signal having reduced noise by strengthening the voice signal having reduced noise in at least a part of the harmonics detected by the harmonic detector according to the input voice signal.
