Abstract

The invention discloses a text error correction and completion method suitable for legal hotline speech recognition, and the method comprises the steps: carrying out the word segmentation and phoneticnotation on an initial text of speech recognition, and obtaining a to-be-corrected text; calculating an editing distance between the to-be-corrected text and the legal vocabulary, and predicting theto-be-corrected text to obtain a first probability prediction value; performing weighted scoring on the editing distance value, the associated semantic weight value and the first probability prediction value by using a scoring method to obtain a first score and a second score; judging whether error correction is needed or not according to the first score, and correcting; and judging whether complementation is needed or not according to the second score, and complementing the text. A pre-trained language model and calculation of an editing distance are adopted, so that the problem of speech recognition mistakes and omissions in the legal field can be solved in a targeted manner, and effective error correction is performed. Besides, when speech recognition error correction is carried out, speech recognition texts in the legal field are complemented, semantics of the speech recognition texts are complemented completely, and subsequent understanding and use are facilitated.

Description

technical field [0001] The invention belongs to the technical field of voice recognition, in particular to a text error correction and completion method suitable for legal hotline voice recognition. Background technique [0002] Speech recognition for the specific scenario of legal hotlines, for example, when dialing 12348, 12368 and other judicial service hotlines, due to the lagging development of telephone speech recognition, users' lack of familiarity with the law, and local accents, etc., real-time speech recognition during hotline calls Errors and omissions are prone to occur. At present, there is no perfect and easy-to-use speech recognition and text error correction method for legal hotline scenarios. The legal hotline field is a professional field, and general methods are not effective in this field. Moreover, the existing text error correction method for speech recognition does not provide a complementary method. If there is a complete vocabulary omission in the sp...
