Problems solved by technology

Online oral language learning platforms are more and more popular with ordinary users because of their free time and low cost. For oral language learning platforms, if the number of users does not increase, the number of teachers will inevitably lead to a shortage of individual user resources. In today's society, The cost of labor is getting higher and higher, how to effectively monitor the learning situation of users has become an important issue on the oral learning platform
[0003] At the same time, the user a

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] figure 1 It is a schematic diagram of the user online learning monitoring process based on voiceprint recognition in the present invention.

[0022] See figure 1 The user online learning monitoring method based on voiceprint recognition provided by the present invention comprises the following steps:

[0023] S101: When a user registers an account through the online learning system, collect the user's voice and extract voiceprint features. Voiceprint refers to the identity information contained in a person's voice. Voiceprint authentication, also known as speaker confirmation, is a type of automatic speaker recognition, that is, the speaker's identity is automatically confirmed through voice. Voiceprint features can use short-term cepstrum parameters, such as Mel cepstrum parameters: (X 0 ,...,X i ,…X N-1 ), where X i Represents the Mel ce...

Abstract

The invention discloses a method for user online study monitoring based on voiceprint recognition. The method comprises the following steps: firstly, collecting the voice of a user and extracting voiceprint characteristic when the user registers an account through an online study system; secondly, creating a voiceprint model for the current account of the user according to the voiceprint characteristic of the users based on a universal user voiceprint model; thirdly, uploading the monitored user voice to a server each time the user logs in the system to perform oral learning; and fourthly, extracting the voiceprint characteristic of the voice and performing match with the voiceprint model registered by the user, a successful match proofs that the user himself is learning, otherwise, an alarm is sent in time and the user is reminded. The method for user online study monitoring based on voiceprint recognition, provided by the invention, through collecting voice during oral learning of the user and extracting voiceprint characteristic, can perform real-time monitoring on user identity, protect account safety of the user, and monitor oral learning condition of the users.

Description

technical field [0001] The invention relates to a user online learning monitoring method, in particular to a user online learning monitoring method based on voiceprint recognition. Background technique [0002] Computer-assisted language learning (CALL for short) is to carry out classroom teaching and assist extracurricular exercises according to the language teaching plan and content arranged in advance by people. As early as around 1955, people were discussing how to use computers for education. Now, the combination of computer-assisted language teaching and long-distance network is widely used in oral language learning. Online oral language learning platforms are more and more popular with ordinary users because of their free time and low cost. For oral language learning platforms, if the number of users does not increase, the number of teachers will inevitably lead to a shortage of individual user resources. In today's society, The cost of labor is getting higher and h...
