US 12,002,475 B2 · Electronic device performing speaker recognition and control method thereof

Abstract

The present disclosure provides an electronic device and a control method thereof. The electronic device of the present disclosure includes: a memory in which a speaker model including acoustic characteristics and context information of a first user voice is stored; and a processor for comparing a degree of similarity between the acoustic characteristics of the first user included in the speaker model and the acoustic characteristics of a second user voice, with a threshold value changing according to a degree of similarity between the context information included in the speaker model and the context information of the second user voice, and then performing authentication on the second user voice.

Dependent claims

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.
