Abstract

A method and an electronic device for recognizing voice are disclosed. The method comprises: receiving an input sequence; determining an output sequence corresponding to the input sequence according to an attention-based sequence-to-sequence model; selecting a target attention head from among a plurality of attention heads of the attention-based sequence-to-sequence model; detecting at least one error output token among output tokens constituting the output sequence based on the target attention head, correcting the output sequence based on the at least one error output token, and outputting the corrected output sequence.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2020-0062450 filed with the Korean Intellectual Property Office on May 25, 2020, the entire disclosure of which is hereby incorporated by reference for all purposes. technical field [0002] The following description relates to methods and electronic devices for recognizing speech. Background technique [0003] In speech recognition technology, in order to solve the problem of generating an output of an undetermined length in response to an input speech of an undetermined length sequence, an encoder-decoder artificial neural network model (one of the sequence-to-sequence models) has been introduced. However, as the length of input speech increases, the accuracy of speech recognition may decrease. Contents of the invention [0004] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not i...
