Abstract

The invention provides an entity error correction method and system for a voice transcription text. The method comprises the following steps: carrying out pinyin labeling on entity vocabularies extracted from a target voice transcription text; clustering the entity vocabularies by utilizing the marked pinyin and an editing distance based on pinyin similarity to generate a clustering result; and determining the entity vocabulary with the highest occurrence frequency in the same category in the clustering result as a standard entity vocabulary, and replacing other entity vocabularies in the category with the standard entity vocabulary. Entity vocabularies are clustered by utilizing an editing distance based on pinyin similarity; the pinyin similarity is taken as a reference factor and the pinyin similarity is added into an editing distance algorithm; the ability of distinguishing synonyms and phonetic words is enhanced, the clustering result better conforms to the actual situation of thevoice transcription text, other entity vocabularies are replaced with the entity vocabularies with the highest occurrence frequency in the same category according to the clustering result, error correction of the voice transcription text is achieved, and then the accuracy of the final voice transcription text is improved.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a method and system for entity error correction of speech transcription text. Background technique [0002] With the promotion and deepening of artificial intelligence (AI, Artificial Intelligence) technology, a batch of intelligent products represented by live working robots and AI controllers have taken the lead in entering the electric power industry and exerted great effectiveness. Therefore, it is the current development trend to combine artificial intelligence technology with power, energy and other industries to promote the transformation and upgrading of traditional industries. Speech is the most natural and effective way for humans to communicate, making speech recognition technology a popular research direction. At present, a large number of call records are generated in the State Grid customer service center every day. The speech of these calls is automatica...
