Abstract

Disclosed are a method and anapparatus for correcting a speech recognition error. The speech recognition error correction method includes determining a likelihood that a speech recognition result is erroneous, and if the likelihood that the speech recognition result is erroneous is higher than a predetermined standard, generating a parallel corpus according to whether the speech recognition result matches the correct answer corpus, generating a speech recognition model based on the parallel corpus, and correcting an erroneous speech recognition result based on the speech recognition model and the language model. Accordingly, speech recognition errors are corrected.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2012-0141972 filed on December 7, 2012, the entirety of which is incorporated herein by reference. technical field [0002] The present invention relates to a method and device for correcting errors in speech recognition, and in more detail relates to a method and device for correcting errors in speech recognition for correcting errors in a speech recognition device. Background technique [0003] Due to the popularity of mobile devices such as smartphones and tablets, there has been increased interest in speech recognition applications (eg, dialog systems like Apple's SIRI). However, the accuracy of the current speech recognition technology is not high, thus frequent speech recognition errors, which lead to malfunctions in the speech recognition application software. Contents of the invention [0004] The object of the present invention to solve the above problems is to provide a speech recogniti...
