The present invention relates to an electronic device that acquires user sound signals by outputting a test sound signal to an external speaker when it is determined that correction of acoustic echo cancellation is required for a sound signal received through a sound receiver, determining a correction value on the basis of a characteristic difference between the test sound signal and a feedback sound signal received from the external speaker in response to the test sound signal, and performing acoustic echo cancellation reflecting the correction value on the sound signal received through the sound receiver. La présente invention concerne un dispositif électronique qui acquiert des signaux sonores d'un utilisateur en émettant un signal sonore de test vers un haut-parleur externe lorsqu'il est déterminé que la correction d'annulation d'écho acoustique est requise pour un signal sonore reçu par l'intermédiaire d'un récepteur sonore, détermine une valeur de correction sur la base d'une différence caractéristique entre le signal sonore de test et un signal sonore de rétroaction reçu en provenance du haut-parleur externe en réponse au signal sonore de test, et réalise une annulation d'écho acoustique reflétant la valeur de correction sur le signal sonore reçu à travers le récepteur sonore. 본 발명은 음성 수신부를 통하여 수신되는 사운드 신호에 대한 에코제거의 보정이 필요하다고 판단되는 경우, 테스트 사운드 신호를 외부 스피커로 출력하고, 테스트 사운드 신호 및 테스트 사운드 신호에 대응하여 외부 스피커로부터 수신되는 피드백 사운드 신호 간의 특성 차이에 기초하여 보정값을 결정하고, 음성 수신부를 통하여 수신되는 음성 신호에 대하여 보정값을 반영한 에코제거를 수행함으로써, 사용자 음성 신호를 획득하는 전자장치에 관한 발명이다.
