Abnormal score detection method and device, equipment and computer readable storage medium

Abstract

The invention provides an abnormal score detection method and device, equipment and a computer readable storage medium. The method comprises the steps of obtaining an audio answer corresponding to a target question and text content of the audio answer; based on the text content, performing multi-modal feature extraction on the audio answer to obtain a first multi-modal feature of the audio answer; acquiring a second multi-modal feature of a reference audio corresponding to the target question; matching the first multi-modal feature of the audio answer with the second multi-modal feature of the reference audio, and determining a reference score of the audio answer based on a matching result; and obtaining an original score of the audio answer, and performing anomaly detection on the original score based on the reference score to obtain a detection result used for representing whether the original score is abnormal or not. According to the method and the device, the abnormal score can be effectively detected.

Description

technical field [0001] The present application relates to artificial intelligence technology, and in particular to a method, device, equipment and computer-readable storage medium for detecting abnormal scores. Background technique [0002] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. More and more artificial intelligence products have the function of scoring questions and answers. Questions and answers scoring can be applied to various voice scoring systems, such as encyclopedia question answering systems, language testing systems for language education applications, oral test systems, and so on. [0003] For the speaking test system, it adopts the man-machine dialogue method. Candidates only need to use the computer and heads...

AI Technical Summary

Problems solved by technology

[0003] For the speaking test system, it adopts the man-machine dialogue method, and candidates can complete the answering of the speaking test questions and automatic intelligent scoring only through the computer and headset equipment, because the audio answers of the open questions in the speaking test are diverse Therefore, this kind of fully automatic intelligent scoring may have inaccurate scoring. However, related technologies still lack effective means for abnormal detection of scoring
