Title:
ERROR CORRECTION DEVICE, ERROR CORRECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/162767
Kind Code:
A1
Abstract:
The present invention provides a high-accuracy error correction technology of a speech recognition result. This error correction device comprises: a first distributed representation sequence generation unit that generates, from a first token sequence representing a speech recognition result, a first distributed representation sequence being a sequence of distributed representations of tokens being elements of the first token sequence; a second distributed representation sequence generation unit that generates, from an input speech-related data sequence being a sequence of acoustic feature amounts of speech or vectors generated from the speech, a second distributed representation sequence being a sequence of distributed representations of input speech-related data being elements of the input speech-related data sequence; a distributed representation sequence integration unit that generates an integrated distributed representation sequence being a sequence of distributed representations including distributed representations being elements of the first distributed representation sequence and the second distributed representation sequence; an encoding unit that generates, from the integrated distributed representation sequence, an encoded integrated distributed representation sequence being a sequence of distributed representations corresponding to the input speech-related data and the feature of the speech recognition result; and a decoding unit that generates, from the encoded integrated distributed representation sequence, a second token sequence representing an error correction result of the speech recognition result.
