Abstract

The invention relates to a language recognition method and device, a server and a storage medium. The method comprises the steps: obtaining acoustic features in a to-be-detected audio signal; inputting the acoustic features into a pre-trained voiceprint feature extraction network model to obtain features output by a target neural network layer in the pre-trained voiceprint feature extraction network model, and taking the features as voiceprint features in the to-be-detected audio signal; determining a log-likelihood ratio between the to-be-detected audio signal and each preset language audio signal according to the voiceprint characteristics in the to-be-detected audio signal and the voiceprint characteristics in each preset language audio signal; determining the feature similarity betweenthe to-be-detected audio signal and each preset language audio signal according to each log-likelihood ratio; and determining the language information of the to-be-detected audio signal from the language information corresponding to each preset language audio signal according to the feature similarity. By adopting the method, the accuracy of language recognition can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of speech recognition, and in particular to a language recognition method, device, server and storage medium. Background technique [0002] With the development of Internet technology, there are many kinds of videos on the Internet, including videos with information in different languages. Users in different regions have completely different preferences for videos with information in different languages. Language information is very important. [0003] In related technologies, the language identification method is generally to manually identify the language information of the audio signal in the video; however, errors are prone to occur through manual identification of the language information, resulting in low accuracy of language identification. Contents of the invention [0004] The present disclosure provides a language recognition method, device, server and storage medium to at least solve t...
