Speech-based scoring method and related device

Abstract

This application provides a voice-based scoring method and related devices, by inputting the voice feature data of the target user's answer to the question of changing money into the trained voice recognition model, the recognition answer data is determined; the index feature data of the recognition answer data is extracted , first feature data and second feature data; input the index feature data into the trained accuracy model to determine the recognition accuracy; input the first feature data into the trained first classification model to determine the first probability data, and input the second feature data into the trained second classification model to determine the second probability data; process the first probability data and the second probability data according to the recognition accuracy to obtain Target probability data: scoring the target user based on the category corresponding to the highest probability in the target probability data to obtain a target score. The subjective influence of artificial phonemes is eliminated, and the accuracy of scoring is greatly improved.

Description

Technical field [0001] The present application relates to the field of speech recognition, in particular a speech-based scoring method and related devices. Background [0002] Population aging is a serious challenge facing all countries in the world, and China, as the most populous country in the world, has become more and more serious in terms of population aging. Studies have shown that mild cognitive dysfunction (Mild CognitiveImpairment, MCI) is a state between normal aging and Alzheimer's disease, the elderly with MCI are at high risk of Alzheimer's disease, about 10%-30% of patients with mild cognitive impairment turn into Alzheimer's disease every year, if the cognitive impairment of the elderly is screened early, the cognitive impairment is diagnosed as early as possible, and early intervention is carried out, It may delay the formation of Alzheimer's disease, so screening for cognitive impairment in the elderly is of great significance. [0003] At present, the internati...

Problems solved by technology

[0003] At present, the representative international screening and evaluation tool for MCI is the Montreal Cognitive Assessment Scale MoCA, which has solid theoretical support and wide clinical application. The traditional method is that the tester conducts written or oral tests on the testees. However, when the testee answers the subjective question of "finding money", different testers may have significant differences in the scores of the testee, which not only wastes a lot of manpower but also seriously affects the quality of diagnosis
