EXAMINATION CHEATING RECOGNITION METHOD AND APPARATUS BASED ON SPEECH RECOGNITION, AND COMPUTER DEVICE

摘要

An examination cheating recognition method and apparatus based on speech recognition, and a computer device. The method comprises: acquiring, from basic speech information of each examinee, a speech feature parameter of each piece of statement pronunciation, and performing dimension reduction to obtain a dimension-reduced feature parameter; training an initialized voiceprint verification model according to the dimension-reduced feature parameter; using the voiceprint verification model to verify whether a target dimension-reduced feature parameter of speech information to be analyzed is consistent with a dimension-reduced feature parameter of a corresponding examinee; determining whether a cheating word is included in target text information that is obtained by means of performing speech recognition on the speech information to be analyzed; and if a voiceprint verification result indicates inconsistency or a text determination result indicates that a cheating word is included, determining that there is a cheating behavior, and sending alarm prompt information. In the method, speech information to be recognized of a examinee is recognized on the basis of speech recognition, so as to realize real-time and accurate determination of a communication cheating behavior between examinees.
