Network teaching method and system with voice recognition function

Abstract

The invention provides a network teaching method and system. Double identity verification of face recognition and voice recognition is realized, the voice signal collection accuracy in a teaching process, an oral training process, a test process and an examination process are scored and assessed by a plurality of models, so that the assessment accuracy is improved, the network teaching is more autonomous and effective, and particularly in reading and listening and recitation teaching, the authenticity and effectiveness of learning can be improved by these functions of the system. By adopting the method provided by the invention, the face recognition is combined with the voice recognition, the user identity is checked before an oral test or system login of the user, and the user can be better encouraged to carry out a human voice test in a use process.

Description

technical field [0001] The invention relates to a network teaching system with voice recognition function and the system. Background technique [0002] In recent years, with the popularization of the mobile Internet and the rapid development of the network teaching system, the traditional teaching mode has gradually been unable to meet the needs of users for multimedia information teaching methods. In the online teaching process, the real-time synchronous display of the teaching process, the real-time recording of the teaching process, and the fast and effective on-demand playback are more and more concerned by the majority of users. In the prior art, in order to meet the above needs, many solutions have been proposed in terms of synchronous display and recording: [0003] Prior Art 1 ("Chinese Journal of Image and Graphics", Volume 8, No. 9, September 2003, Zhang Liping, etc., "a screen sharing scheme based on screen copying and compression technology") discloses common sc...

Problems solved by technology

This is because most of the existing network teaching systems use video streams and manual screenshots by teachers according to their own judgments in the process of transmitting data on the same screen. Concurrent network transmission often has slow speed, unsmooth display, and data freezes, which affect the students' experience in class, and teachers have to consider timely screenshots while lecturing, and sometimes forget to take screenshots and send them to students. Students can't judge whether they have obtained timely screenshots, which affects the teaching effect

[0012] Specifically, the shortcomings include: 1. The recording process is cumbersome, and some require special personnel to record on-site; 2. The video file is huge, and the quality of the courseware needs to be sacrificed for multiple format conversions to reduce the file size; 3. The
