Abstract

The present application discloses a speech recognition method, device, electronic device and storage medium, and relates to the technical field of speech recognition. The specific implementation scheme is: perform speech recognition on the input speech to obtain initial text data; recognize formula fragments in the initial text data; perform grammar parsing on the formula fragments to obtain a grammar tree corresponding to the formula fragments; Describe the grammar tree to obtain the formula translation result corresponding to the formula fragment; replace the formula fragment in the initial text data with the formula translation result to obtain the speech recognition result corresponding to the voice. The present application obtains the grammar tree corresponding to the formula fragment by performing grammar analysis on the obtained formula fragment, and then obtains the formula translation result corresponding to the formula fragment according to the grammar tree. Accurately rewrite and unify, and solve the recognition and translation of complex formulas.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of speech recognition technology, and in particular to a speech recognition method, apparatus, electronic device and storage medium. Background technique [0002] With the maturity of voice recognition technology, voice input form has been widely used, such as voice input method and voice search. However, for the recognition of query sentences in professional fields (such as mathematics, physics, etc.), due to a large number of formulas, the effect of speech recognition is still not ideal, and only literal information can be recognized, but structured formulas cannot be understood. [0003] There are mainly two methods for recognizing speech containing formulas in the prior art: [0004] The first is the recognition method based on template matching, that is, after the speech is converted into the initial text, the initial text is matched with the template,...
