AI 'Speech Clock' Links Vocal Patterns to Biological Aging and Dementia Risk
A new AI tool called a 'speech clock' can estimate a person's biological age and dementia risk by analyzing voice recordings. Published in Science Advances, the study found that discrepancies between chronological age and 'speech age' correlate with brain atrophy, DNA methylation, and Alzheimer's biomarkers. Researchers suggest this low-cost method could eventually replace expensive medical tests for monitoring cognitive decline.
