Electronic device, method, and computer-readable storage medium for identifying speech signal corresponding to designated text

Abstract

A processor of an electronic device according to an embodiment may be configured to acquire, from a first neural network to which a speech signal received via a microphone has been input, a first sequence of feature information about portions, corresponding to designated frame units, of the speech signal. The processor may be configured to acquire, from a second neural network to which a designated text has been input, a second sequence of one or more phonetic symbols for the designated text. The processor may be configured to acquire, from a third neural network to which the first sequence and the second sequence have been input, a first parameter indicating the degree of correspondence between the voice signal and the designated text. The processor may be configured to acquire one or more second parameters indicating the degree of correspondence the portions of the voice signal have with respect to each of the one or more phonetic symbols included in the second sequence.
