Automated pause analysis of connected speech from story recall as markers of cognitive decline
Participants with MCI produced shorter SR samples with a larger percentage and duration of pauses than CU participants. Shorter speech duration correlated with higher amyloid-beta levels. This contrasts with the longer CT speech duration in the MCI group, possibly due to SR's episodic memory demands. Automated, acoustic-based pause analysis shows promise as an early AD marker, warranting further study in larger, diverse cohorts.
