Embodiment Construction

[0049] As mentioned in the background art, the accuracy of existing language recognition methods needs to be improved.

[0050] In the language recognition method, text, voice or image can be used alone for language recognition, wherein the use of image for language recognition can be to recognize the lip shape in the image and recognize the lip language. Normally, the accuracy of speech recognition is high, but when the ambient noise is high, or the quality of the recording device needs to be improved, the accuracy of speech recognition will be relatively poor. Therefore, the accuracy of language recognition using text, voice or image alone needs to be improved.

[0051] In some application scenarios, such as in the network learning scenario, it is necessary to identify the language used by the user when learning, so as to judge the user's learning situation. In this scenario, it is usually possible to obtain videos of users learning.

[0052] When the user is learning onli...

Abstract

The embodiment of the invention discloses a language identification method and device, a language identification training method and device, a medium and a terminal. The language identification methodcomprises: acquiring a speech identification feature of a to-be-identified video and a lip language identification feature; identifying the speech identification feature to obtain a speech phoneme sequence, and calculating the speech language type probability of the speech phoneme sequence as a preset language; identifying the lip language identification feature to obtain a lip language phoneme sequence, and calculating the lip language type probability of the lip language phoneme sequence as a preset language; and determining the language type of the to-be-identified video according to the speech language type probability and the lip language type probability. The technical solution in the embodiment of the invention has higher identification accuracy.

Description

technical field [0001] The invention relates to the field of computers, in particular to a language recognition method and device, a training method and device, a medium, and a terminal. Background technique [0002] Pattern recognition is a basic intelligence of human beings. In daily life, people often carry out "pattern recognition". With the development of computer technology and the rise of artificial intelligence, the use of computers to replace humans for pattern recognition has developed rapidly and become a new technical discipline. [0003] Language recognition is a kind of pattern recognition, and the language recognition technology is mainly used to detect the language classification of the input information. The accuracy of existing language recognition methods needs to be improved. Contents of the invention [0004] The technical problem solved by the embodiments of the present invention is to improve the accuracy of the language recognition method. [000...
