Abstract

The invention discloses an intelligent speech recognition method and device based on classification identification and related equipment, and the method comprises the steps: carrying out the endpoint detection and feature extraction of original speech data, so as to obtain speech feature data; identifying the industry attribute of the original voice data through the attached industry attribute identifier when the original voice data is input; recognizing the voice feature data through a trained universal voice recognition model to obtain a recognition result; judging whether the confidence coefficient in the recognition result is lower than a preset value or not; inputting the corresponding text of which the confidence coefficient is lower than a preset value into the corresponding industry vertical module for optimization identification; and selecting the text corresponding to the maximum confidence coefficient as a final recognition result according to the confidence coefficient in the recognition result and the optimized confidence coefficient. The industry attribute identifier is attached when the original voice data is input, so that a corresponding industry vertical module can be conveniently called subsequently to carry out optimization identification; manual labeling is not needed, and high accuracy is maintained through secondary verification, recognition and correction.

Description

technical field [0001] The invention relates to the technical field of speech recognition and semantic understanding of artificial intelligence natural language processing, and in particular to an intelligent speech recognition method, device and related equipment based on classification marks. Background technique [0002] Speech recognition technology is a technology that allows machines to convert voice signals into corresponding text or commands through the process of recognition and understanding. The general working principle and process of the general speech recognition system include: endpoint detection, feature extraction technology, pattern matching criteria, model training technology, etc. First, a specific acoustic model is identified through feature extraction technology and pattern matching technology; then a certain language model is formed through model training. In the process of modeling, a large number of speech databases and language databases (involving...
