Electronic apparatus and controlling method thereof

Abstract

An electronic apparatus includes a microphone; a speaker; a memory storing at least one instruction; and one or more processors operatively coupled to the memory and the speaker, wherein the one or more processors are configured to execute the at least one instruction to: based on identifying that a first voice sensed through the microphone corresponds to a wake-up voice, convert a state of the electronic apparatus from a standby state to a wake-up state, based on a second voice being sensed while the state of the electronic apparatus is the wake-up state, identify a first user query included in first voice data obtained based on the second voice, perform a first operation corresponding to the first user query, identify a predetermined query corresponding to the first user query, obtain a query list including at least one query based on the predetermined query and user context information, identify a second user query included in second voice data obtained based on a third voice sensed through the microphone, and based on a first semantic similarity between the second user query and the at least one query of the query list being greater than or equal to a predetermined value, perform a second operation corresponding to the second user query and maintain the state of the electronic apparatus as the wake-up state.
