Abstract Provided are a user authentication method and a user authentication apparatus. According to some embodiments of the present invention, the method for authenticating a user using an electronic device includes the operations of: obtaining an input audio signal based on an utterance input of the user; discriminating, from the input audio signal, an audio signal in at least one utterance section and an audio signal in at least one non-utterance section; generating environment information indicating an environment from which the utterance input is received, based on the audio signal in the non-utterance section; adjusting an authentication criterion for authenticating the user based on a comparison result between the generated environmental information and registration environment information indicating an environment from which an utterance input corresponding to a registered audio signal previously registered for the user is received; and authenticating the user based on the adjusted authentication criterion and the input audio signal. 사용자 인증 방법 및 장치가 제공된다. 본 개시의 일부 실시예에 따른 전자 장치가 사용자를 인증하는 방법은, 사용자의 발화 입력에 기초하여 입력 오디오 신호를 획득하는 동작, 상기 입력 오디오 신호로부터, 적어도 하나의 발화 구간의 오디오 신호 및 적어도 하나의 비 발화 구간의 오디오 신호를 구별하는 동작, 상기 비 발화 구간의 오디오 신호에 기초하여, 상기 발화 입력이 수신된 환경을 나타내는 환경 정보를 생성하는 동작, 상기 생성된 환경 정보 및 상기 사용자에 대하여 미리 등록된 등록 오디오 신호에 대응되는 발화 입력이 수신된 환경을 나타내는 등록 환경 정보의 비교 결과에 기초하여, 상기 사용자를 인증하기 위한 인증 기준을 조정하는 동작 및 상기 조정된 인증 기준 및 상기 입력 오디오 신호에 기초하여 상기 사용자를 인증하는 동작을 포함할 수 있다.
