The invention discloses a voice recognition method, a voice recognition device, electronic equipment and a storage medium, and relates to the technical field of voice recognition. The method specifically comprises the following steps of performing voice recognition on input voice to obtain initial text data; recognizing a formula fragment in the initial text data; performing grammar parsing on theformula fragment to obtain a grammar tree corresponding to the formula fragment; obtaining a formula translation result corresponding to the formula fragment obtained on the basis of the grammar tree; and replacing the formula fragment in the initial text data into the formula translation result to obtain the voice recognition result corresponding to the voice. The gramma parsing is performed onthe obtained formula fragment to obtain the grammar tree corresponding to the formula fragment; the formula translation result corresponding to the formula fragment is obtained according to the grammar tree; the sufficient understanding on the mutual relationship of each part of the formula can be realized; the formula is subjected to more thorough and more precise rewrite and normalization; and the problem of recognition and translation of a complicated formula is solved.
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, device, electronic equipment and storage medium. Background technique [0002] With the maturity of voice recognition technology, the input form of voice has been widely used, such as voice input method and voice search. However, for the recognition of query statements in professional fields (such as mathematics, physics, etc.), due to the large number of formulas, the speech recognition effect is still not ideal. It can only recognize literal information and cannot understand structured formulas. [0003] In the prior art, there are mainly two methods for recognizing speech containing formulas: [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, ...
