Abstract
(EN)
A voice processing method and apparatus, a storage medium, and an electronic device. The method comprises: obtaining a reverberation voice signal (101); performing signal fidelity processing on the reverberation voice signal to obtain a first voice signal (102); performing Fourier transformation on the first voice signal to obtain a phase spectrum corresponding to the first voice signal and a first power spectrum (103); calculating a second power spectrum according to the first power spectrum (104); and constructing a target clean voice signal according to the phase spectrum and the second power spectrum (105).
(FR)
L'invention concerne un procédé et un appareil de traitement vocal, un support de stockage et un dispositif électronique. Le procédé consiste à : obtenir un signal vocal de réverbération (101) ; effectuer un traitement de fidélité de signal sur le signal vocal de réverbération pour obtenir un premier signal vocal (102) ; effectuer une transformée de Fourier sur le premier signal vocal pour obtenir un spectre de phase correspondant au premier signal vocal et un premier spectre de puissance (103) ; calculer un second spectre de puissance en fonction du premier spectre de puissance (104) ; et construire un signal vocal propre cible en fonction du spectre de phase et du second spectre de puissance (105).
