Abstract
(EN)
The application provides a method and apparatus for speech recognition. The method comprises: with Chinese-character-based speech recognition, speech recognition is carried out on to-be-recognized named entity speech to identify a Chinese character sequence of a Chinese character recognition result of the to-be-recognized named entity speech; with Chinese-phonetic-alphabet-based speech recognition, speech recognition is carried out on the to-be-recognized named entity speech to identify a Chinese phonetic alphabet sequence of a Chinese phonetic alphabet identification result of the to-be-recognized named entity speech; according to the identified Chinese character sequence and the identified Chinese phonetic alphabet sequence, similarity degrees between all candidate named entities in a specific named entity list and the to-be-recognized named entity speech are determined; and on the basis of the similarity degrees between all candidate named entities in a specific named entity list and the to-be-recognized named entity speech, a speech recognition result of the to-be-recognized named entity speech is determined from the specific named entity list. Therefore, accuracy of identification of the named entity speech can be improved.
