US 2021/0174813 A1 · VOICE INPUT AUTHENTICATION DEVICE AND METHOD

Abstract

Provided are a method of authenticating a voice input provided from a user and a method of detecting a voice input having a strong attack tendency. The voice input authentication method includes: receiving the voice input; obtaining, from the voice input, signal characteristic data representing signal characteristics of the voice input; and authenticating the voice input by applying the obtained signal characteristic data to a first learning model configured to determine an attribute of the voice input, wherein the first learning model is trained to determine the attribute of the voice input based on a voice uttered by a person and a voice output by an apparatus.

Dependent claims

A device for authenticating a voice input provided from a user, the device comprising:

a microphone configured to receive the voice input;
a memory configured to store one or more instructions;
and
a processor configured to execute the one or more instructions,
wherein the processor is further configured to execute the one or more instructions to obtain, from the voice input, signal characteristic data representing signal characteristics of the voice input, and authenticate the voice input by applying the obtained signal characteristic data to a first learning model configured to determine an attribute of the voice input, and
wherein the first learning model is trained to determine the attribute of the voice input based on a voice uttered by a person and a voice output by an apparatus.
