Electronic device and controlling method of electronic device

Abstract

Provided are an electronic device and a method of controlling an electronic device. The electronic device includes: a memory storing at least one instruction; and at least one processor configured to execute the at least one instruction, wherein one or more of the at least one processor is configured to: acquire a first vector corresponding to each of a plurality of sections of a voice signal by inputting the voice signal to a common encoder based on acquiring the voice signal; acquire a second vector corresponding to each of the plurality of sections and independent on a context of the voice signal by inputting the first vector into a first individual encoder; acquire a phoneme sequence corresponding to the second vector by inputting the second vector into a first decoder; acquire a third vector corresponding to at least two sections among the plurality of sections and dependent on the context of the voice signal by inputting the first vectors into a second individual encoder; acquire a sub-word sequence corresponding to the third vector by inputting the third vector into a second decoder; and acquire text information corresponding to the plurality of sections by correcting the sub-word sequence based on the phoneme sequence, through a text information acquisition module.
