Abstract

The present invention provides a speech recognition system optimization method, device and electronic equipment, wherein the speech recognition system includes a speech conversion model and a semantic recognition model, and the speech recognition system optimization method includes: determining the word error rate of the first text, And determine the actual accuracy rate of semantic recognition of the first text by the semantic recognition model, wherein the first text is the text converted from the audio file by the speech conversion model; according to the word error rate, determining the target accuracy rate of the semantic recognition model; optimizing the semantic recognition model or the speech conversion model based on the target accuracy rate and the actual accuracy rate. The solutions provided by the embodiments of the present invention can at least solve the problem of high cost of model optimization in the prior art.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to an optimization method, device and electronic equipment of a speech recognition system. Background technique [0002] In the prior art, the voice recognition process in the intelligent electronic device is usually: converting the user's voice into text through the voice conversion model, and then performing semantic recognition on the text through the semantic recognition model, so as to determine the user's intention. However, since there may be conversion errors in the result of speech conversion, at this time, the subsequent semantic recognition process may be inaccurate. In addition, the semantic recognition process itself also has errors. When it is necessary to improve the accuracy of speech recognition, in the prior art, since it is impossible to determine which link’s model needs to be optimized, it is only possible to blindly optimize and test the models of eac...
