| Outline of Final Research Achievements |
In this research, we have developed a novel data-mining approach for detection of cognitive impairment, SPCIR (Speech Prosody-Based Cognitive Impairment Rating), which can discriminate between mild cognitive impairment and mild Alzheimer’s disease from elderly using prosodic sign extracted from elderly speech during questionnaire test. This study proposes a binary discrimination model of SPCIR using multivariate logistic regression and model selection using receiver operating characteristic (ROC) curve analysis, and confirmed acceptable discriminative performance of the sensitivity and specificity of SPCIR for diagnosis (control; mild cognitive impairment/mild Alzheimer’s disease).
