1. An electronic device, comprising:
a microphone;
a memory configured to store a speaker model comprising acoustic features of a first user voice and context information comprising information on phoneme of the first user voice; and
a processor configured to:
based on a second user voice being input through the microphone, perform an authentication on the second user voice by comparing a similarity between acoustic features of the first user voice included in the speaker model and acoustic features of the second user voice with a threshold value determined to be proportional to a similarity between the context information included in the speaker model and context information of the second user voice, the context information of the second user voice comprising information on phoneme of the second user voice.
