Problems solved by technology

However, the current speech recognition model is rarely trained for user-level models, and the way to optimize the model is not flexible enough. The support for user-level language habits is very low, which seriously affects the user experience.
[0003] How to quickly accumulate user-level corpus, quickly build a user-level language model, solve the problem of poor support for user-level speech recognition, avoid cold starts caused by too few user sentences, and provide better user-level speech recognition has become an urgent problem to be solved

Abstract

The present invention discloses a method and device for speech recognition. The method includes: step 101, acquiring the speech recognition models of multiple users; step 102, performing statistics on the speech recognition models of the multiple users, and determining that the similarity is greater than N user sets equal to the first threshold, where N is an integer greater than or equal to; step 103, perform corpus training on the speech recognition models of the i-th user set to generate the i-th user set speech recognition model, 1≤i≤N. Through the method of the present invention, the commonality of similar users can be used to quickly accumulate user-level corpus, quickly build a user-level language model, solve the problem of poor support for user-level speech recognition, and avoid cold starts caused by too few user sentences, providing Better user-level speech recognition effect improves user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of voice interaction, and in particular, to a voice recognition method and device. Background technique [0002] In recent years, with the development of speech recognition technology, speech recognition technology has entered various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. interact. The speech recognition method is mainly a matching algorithm. In the training stage, the speech recognition model is constructed by continuously accumulating corpus and storing it as a template in the template library. In the recognition stage, the feature vector of the input speech is sequentially compared with the template library. The similarity of each corpus template is compared, and the one with the highest similarity is output as the recognition result. Most of the existing speech recognition technologies only fo...
