Problems solved by technology

Due to the large number of keywords in each scene, coupled with the influence of many factors such as environment and accent, only based on the correlation between words in the language model and the correlation between speech information and pronunciation in the acoustic model, the speech information The candidate recognition results are scored, and the candidate recognition result with the highest score is used as the text information corresponding to the voice information, and the voice recognition result may be inaccurate

Abstract

The invention provides a speech recognition method, a device and a storage medium, which relate to the computer technical field. The method comprises the following steps: acquiring at least two candidate recognition results and scores thereof of speech information to be recognized provided by a current user; extracting key words of preset type from each candidate recognition result according to preset keyword extraction rules; using the extracted key words and the scores of the candidate recognition results, the scores of each candidate recognition result are corrected, and the final recognition result of the speech information to be recognized is determined according to the correction result. As that embodiment of the present application revise the score of the candidate recognition result by using the key word extracted from the candidate recognition result, and the key word is used as a correcting factor, each candidate recognition result can obtain more accurate score, and more accurate recognition results can be screened according to the corrected score.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a voice recognition method, device and storage medium. Background technique [0002] With the development of computer technology, the application of automatic speech recognition (ASR) technology in human-computer interaction and other fields is increasing. At present, speech recognition technology mainly converts speech information to be recognized into text information through signal processing module, feature extraction module, acoustic model, language model (Language Model, LM), pronunciation dictionary and decoder (Decoder), and completes speech recognition. . [0003] Such as figure 1 as shown, figure 1 It is a flow chart of speech recognition in the related art. In the speech recognition process, the speech information to be recognized can be divided into multiple speech information frames, and then each speech information frame is enhanced by processing suc...
