Abstract:
(EN) A voice signal processing method according to an embodiment of the present invention for solving technical problems comprises the steps of: obtaining a real-time near-end noise signal; obtaining a far-end voice signal accompanied by an incoming call; measuring the subjective sound quality and the perceptual-objective sound quality of test signals generated on the basis of a reference signal and the real-time near-end noise signal; selecting at least one sound quality improvement method on the basis of the subjective sound quality and the perceptual-objective sound quality, and determining parameters to be applied to the selected at least one sound quality improvement method; and on the basis of the determined parameters, improving the sound quality of the far-end voice signal by using the selected at least one sound quality improvement method, wherein the test signals are generated by mixing the obtained real-time near-end noise signal with the reference signal in which the sound quality is improved by applying a combination of parameter values to the sound quality improvement methods.
(FR) Selon un mode de réalisation, la présente invention concerne un procédé de traitement de signal vocal destiné à résoudre des problèmes techniques dont les étapes consistent : à obtenir un signal de bruit d’extrémité proche en temps réel ; à obtenir un signal vocal d’extrémité lointaine accompagné d’un appel entrant ; à mesurer la qualité sonore subjective et la qualité sonore objective perceptive de signaux d’essai générés sur la base d’un signal de référence et du signal de bruit d’extrémité proche en temps réel ; à sélectionner au moins un procédé d’amélioration de qualité sonore sur la base de la qualité sonore subjective et de la qualité sonore objective perceptive, et à déterminer des paramètres à appliquer au ou aux procédés d’amélioration de qualité sonore sélectionnés ; et sur la base des paramètres déterminés, à améliorer la qualité sonore du signal vocal d’extrémité lointaine au moyen du ou des procédés d’amélioration de qualité sonore sélectionnés, les signaux d’essai étant générés en mélangeant le signal de bruit d’extrémité proche en temps réel au signal de référence dans lequel la qualité sonore est améliorée en appliquant une combinaison de valeurs de paramètres aux procédés d’amélioration de qualité sonore.
(KO) 상기 기술적 과제를 해결하기 위한 본 발명의 일 실시예에 따른 음성 신호 처리 방법은, 실시간 수신단(near-end) 잡음 신호를 획득하는 단계; 착신 호(incoming call)에 따른 송신단(far-end) 음성 신호를 획득하는 단계; 기준 신호(reference signal) 및 실시간 수신단 잡음 신호에 기초하여 생성된 테스트 신호들의 주관적(subjective) 음질 및 지각-객관적(perceptual objective) 음질을 측정하는 단계; 주관적 음질 및 지각-객관적 음질에 기초하여 적어도 하나의 음질 개선 방법을 선택하고, 선택된 적어도 하나의 음질 개선 방법에 적용될 파라미터들을 결정하는 단계; 및 결정된 파라미터들에 기초하여, 선택된 적어도 하나의 음질 개선 방법을 이용해 송신단 음성 신호의 음질을 개선하는 단계;를 포함하고, 테스트 신호들은 음질 개선 방법들에 파라미터 값들의 조합을 적용하여 음질이 개선된 기준 신호와 획득된 실시간 수신단 잡음 신호를 믹싱하여 생성된다.
