1. A user authentication method, performed by an electronic apparatus, of authenticating a user based on an utterance input, the user authentication method comprising:
obtaining an input audio signal based on the utterance input of the user;
obtaining, from the input audio signal, at least one audio signal of an utterance section and at least one audio signal of a non-utterance section;
calculating a first average energy value of the at least one audio signal of the utterance section, wherein the first average energy value is related to a distance between the user and the electronic apparatus;
calculating a second average energy value of the at least one audio signal of a registration utterance input;
adjusting a threshold for user authentication based on a result of a comparison between the first average energy value and the second average energy value; and
authenticating the user based on the adjusted threshold and the input audio signal.
