Abstract

The invention provides a speech recognition result error correction method and device. The speech recognition result error correction method comprises the steps of carrying out phonetic notation on a speech recognition result to be corrected so as to acquire phonetic transcription corresponding to the speech recognition result; acquiring candidate texts according to the phonetic transcription, and determining an optimal candidate text in the candidate texts; judging whether the optimal candidate text meets a preset condition or not; if the optimal candidate text meets the preset condition, determining the optimal candidate text as a correction result of the speech recognition result to be corrected. The speech recognition result error correction method can improve the accuracy of the correction result.

Description

technical field [0001] The present application relates to the technical field of speech recognition, and in particular to a method and device for correcting errors in speech recognition results. Background technique [0002] Speech recognition is used to recognize speech as text, and error correction of speech recognition results is an important task in the process of speech understanding. Limited by the accuracy of speech recognition, errors often occur in speech recognition results, which will hinder the follow-up work of speech understanding and increase the difficulty of speech understanding. Speech recognition result error correction can correct some recognition error results, thereby improving the accuracy of speech understanding. [0003] At present, there is no mainstream solution for error correction of speech recognition results. Generally, it is a statistical method based on the probability information of word recognition results, and the accuracy of the correcti...
