The application discloses a learner cognitive state evaluation method, system, device and medium based on voice, and belongs to the technical field of remote learning cognitive evaluation. The method comprises the following steps: collecting reference voice, reading voice and answering voice; separating voice micro-tremor features reflecting voice tremor from the reference voice through LPC and ICA analysis methods; reconstructing voice rhythm control features from the reading voice through Hilbert transform and nonlinear dynamics methods; extracting breathing voice coordination efficiency features of the answering voice through energy envelope analysis and phase coordination calculation; mapping the extracted features into initial scores of four cognitive dimensions of attention, fatigue, psychological load and stress level respectively, and making a comprehensive decision to obtain final scores of the four cognitive dimensions of the learner. The application can deeply mine biological markers affecting cognition from the collected voice data, thereby improving the accuracy of the cognitive state evaluation of the learner in remote learning.

The invention discloses a voice-based learner cognitive state assessment method, system and device and a medium, and belongs to the technical field of remote learning cognitive assessment, and the method comprises the steps: collecting a reference voice, a reading voice and an answering voice; voice micro-tremor features reflecting voice tremor are separated from reference voice through LPC and ICA analysis methods, sounding rhythm control features are reconstructed from reading voice through Hilbert transform and a nonlinear dynamics method, and breathing voice cooperation efficiency features of answering voice are extracted through energy envelope analysis and phase coordination calculation; and respectively mapping the extracted features into initial scores of four cognitive dimensions of attention, fatigue degree, psychological load and stress level, and performing comprehensive decision to obtain final scores of four cognitive dimensions of the learner. According to the method, the biomarkers influencing cognition can be deeply mined from the collected voice data, so that the accuracy of evaluating the cognitive state of the learner in remote learning is improved.
