DrivenData Challenge

This page provides access to data from the PREPARE Challenge Phase 2: Acoustic Track. The goal of the overall competition was to improve early prediction of Alzheimer's disease and related dementias (AD/ADRD) using speech data. You can learn more about the overall Challenge and its results here. The competition has now concluded, but the data from the Phase 2 Acoustic Track remain available for research use under DementiaBank terms.

The data can be accessed here

Additional information about the dataset and metadata is available here.
