Problems solved by technology

[0003] At present, the deep learning method used in language recognition model training can be divided into front-end, coding layer and back-end. The front-end represents the input features, the coding layer represents the backbone network, the back-end represents the loss function, and the back-end can be divided into measurement loss and classification. loss, the accuracy and reliability of the deep learning method using the backbone network combined with the metric loss or the backbone network combined with the classification loss are not high, and still need to be further improved

Abstract

The invention discloses a language recognition method and system based on an adaptive central anchor, which includes constructing a language data set; performing enhanced processing on speech data in the language data set; extracting features of the enhanced speech data to generate a feature data set; Constructing a deep neural backbone network, and using a supervised learning method to train the deep neural backbone network based on the classification loss function; based on the metric loss function, using an adaptive central anchor method to further train the deep neural backbone network; based on the trained deep neural backbone network Carry out language recognition; this method expands the data set through data enhancement, and also increases the robustness of the data set; uses a multi-scale fusion residual neural network to enhance the feature expression ability of the backbone network, and uses classification loss and measurement successively The loss further improves the accuracy of recognition.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a language recognition method and system based on an adaptive central anchor. Background technique [0002] With the development of speech signal processing and artificial intelligence, especially the rapid development of deep learning in recent years, the reliability of language recognition technology has been further improved. Many intelligent voice assistants can use automatic language recognition technology to infer the language used by users; As a preprocessing part of many speech processing tasks, language recognition technology has a wide range of applications in the fields of multilingual speech recognition, cross-lingual communication, and machine translation. [0003] At present, the deep learning method used in language recognition model training can be divided into front-end, coding layer and back-end. The front-end represents the input features, the coding ...
