Problems solved by technology

The recognition of general-purpose instructions and system control instructions can be completed by using the existing Mandarin recognition method. However, due to the complexity of equipment control instructions, rich pronunciation types and writing formats, the existing speech recognition method is used to recognize such instructions. For equipment control commands, the recognition effect is poor, resulting in low matching accuracy when the intelligent system, intelligent equipment or inspection robot is docked with the power system

Abstract

The invention provides a voice recognition method and device, electronic equipment and a readable storage medium, and the method comprises the steps: inputting an obtained to-be-recognized voice signal into a pre-trained voice recognition model, and obtaining a recognition text matched with the to-be-recognized voice signal; wherein the speech recognition model comprises an acoustic model and a language model, the language model is generated by interpolation of a basic language model and a special language model, and the special language model is obtained by training a word segmentation text obtained by word segmentation of a structured instruction text, an extended text corresponding to the word segmentation text and an extended pronunciation dictionary corresponding to the word segmentation text; and the expanded pronunciation dictionary is obtained by expanding an initial pronunciation dictionary, and finally a voice instruction corresponding to the recognition text is determined. According to the method, the recognition accuracy of Chinese and English letter mixing, professional vocabularies in the proprietary field and Chinese and few word mixing can be improved, and the matching accuracy when an intelligent system, intelligent equipment or an inspection robot is in butt joint with an electric power system is effectively improved.

Description

technical field [0001] The present application relates to the field of intelligent voice technology, and in particular, to a voice recognition method, device, electronic equipment and readable storage medium. Background technique [0002] The normal operation of the substation is directly related to the stability and safety of the entire power system. With the development of science and technology, more and more intelligent systems, intelligent equipment and inspection robots are applied to the management of substations to improve the safety and accuracy of inspections. , among which, the vast majority of smart devices are controlled by voice commands. [0003] Voice commands used in substations mainly include general commands, system control commands and equipment control commands. The recognition of general-purpose instructions and system control instructions can be completed by using the existing Mandarin recognition method. However, due to the complexity of equipment co...
