Embodiment Construction

[0092] In order to make the above objects, features and advantages of the present application more obvious and understandable, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0093] In order to facilitate understanding and explanation of the technical solutions provided by the embodiments of the present application, the background technology of the present application will first be described below.

[0094] In the research of traditional speech recognition, the inventor found that in some speech recognition systems based on the hidden Markov model, the speech information is decoded through the n-gram language model to generate possible candidate result information, that is, the speech information may corresponding recognition results. Then, the obtained candidate result information is sorted through the n-gram language model, and the optimal candidate resul...

Abstract

The embodiment of the invention discloses a sorting method and device for voice recognition candidate results. The method comprises the steps: acquiring candidate result information of voice recognition; combining the identified candidate result information in pairs to generate at least one candidate combination; identifying common erroneous words of the candidate combinations; replacing a commonerror word included in each candidate result information in the candidate combination with a marker word, replacing word information of the common error word with marker word information, obtaining areplacement candidate result corresponding to each candidate result information, and obtaining a to-be-classified combination; utilizing a pre-trained binary classification model to obtain the advantages and disadvantages of two replacement candidate results in each to-be-classified combination; and sorting the candidate result information according to the advantages and disadvantages of the two replacement candidate results in each to-be-classified combination. By obtaining the advantages and disadvantages of every two replacement candidate results, the advantages and disadvantages sequence of the replacement candidate result information can be determined, and an accurate voice recognition result is obtained.

Description

technical field [0001] The present application relates to the technical field of speech recognition, in particular to a method and device for sorting speech recognition candidate results. Background technique [0002] At present, in the process of speech recognition, firstly, the speech information is converted to obtain multiple candidate result information corresponding to the speech information, and then the obtained multiple candidate result information is sorted, and finally the optimal candidate result information among the sorted results is passed. Get the speech recognition result. [0003] However, the existing sorting methods for candidate result information have the problem of inaccurate sorting results, which makes the optimal candidate result information obtained through the sorting results inaccurate, resulting in a large deviation between the speech recognition result and the speech information . Contents of the invention [0004] In view of this, the embo...
