Longitudinal changes of automated speech markers in MCI and mild AD

Mild cognitive impairment (MCI) and mild Alzheimer’s disease (mAD) are characterized by decline in memory and other cognitive domains, including language. Previous studies have shown that MCI and mAD patients produce impaired speech. In this study, we investigated longitudinal changes in lexical and acoustic speech features from natural speech of MCI and mAD patients using highly reliable automated methods.
