Problems solved by technology

[0002] In the speech recognition process in the related art, the function of identifying specific hot words can be realized, thereby improving the recall rate of the specific hot words in the voice to be recognized, but usually the processing time of the specific hot words is relatively long. Every time a user makes changes to a specific hot word, such as adding a hot word, modifying a hot word, or deleting a hot word, he often has to wait for a long time before he can be recognized according to the specific hot word after the change. voice recognition

Abstract

The invention relates to a voice recognition method and device, a readable medium and electronic equipment, and the method comprises the steps: obtaining a hot word list which comprises one or more to-be-recognized hot words; constructing a weighted finite state converter corresponding to each to-be-recognized hot word in the hot word list through a preset script, wherein the weighted finite stateconverter is a weighted finite state converter in an uncertain state; and loading the weighted finite-state converter into a target speech recognition decoder, so as to recognize the target speech through the target speech recognition decoder. Therefore, the construction of the weighted finite-state converter does not need to carry out compiling steps such as determinalization and the like; the construction speed is greatly increased, so that the processing speed of the to-be-recognized hot words during speech recognition is greatly increased, and a user can adjust the to-be-recognized hot words needing to be added during speech recognition in real time without excessive waiting.

Description

technical field [0001] The present disclosure relates to the field of speech recognition, and in particular, to a speech recognition method, device, readable medium and electronic equipment. Background technique [0002] In the speech recognition process in the related art, the function of recognizing specific hot words can be realized, thereby improving the recall rate of the specific hot words in the voice to be recognized, but usually the processing time of the specific hot words is relatively long. Every time a user makes a change to a specific hot word, such as adding a hot word, modifying a hot word, or deleting a hot word, he often has to wait for a long time to be recognized according to the specific hot word after the change. voice recognition. Contents of the invention [0003] This Summary is provided to introduce a simplified form of concepts that are described in detail later in the Detailed Description. This summary of the invention is not intended to ident...
