generating, based on the in-use user utterance, an in-use audio signal;
generating, for the in-use audio signal, an in-use time-frequency representation thereof;
applying the MLA to the in-use time-frequency representation to generate a distribution parameter between likelihood values respectively indicative of the user producing the in-use user utterance being one of the first user class and the second user class, such that:
in response to the distribution parameter being equal to or greater than a predetermined distribution threshold, determining the user as being of the first user class; and
