A Machine Learning Framework for Cognitive Impairment Screening from Speech with Multimodal Large Models
Leveraging cutting-edge AI to transform early detection of cognitive impairment through speech analysis.
Executive Impact & AI Opportunity
This study proposes a novel, non-invasive, and scalable AI framework for early Alzheimer's disease (AD) screening using speech data. It integrates pre-trained multimodal large language models (CosyVoice2) with structured MMSE speech tasks. Data from 1098 participants in Sichuan and Chongqing were analyzed using 14 machine learning models. LightGBM and Gradient Boosting achieved the highest AUC (0.9501). SHAP analysis identified spectral complexity, energy dynamics, and temporal features as key discriminators. This framework offers an interpretable solution for clinical and telemedicine AD detection.
