Rather than looking at a single property of the voice, the researchers used machine learning to analyse hundreds of features capturing how people speak and what they say: incorporating speech rate and pauses, pitch, emotional content, vocabulary, semantic precision, and the amount and organisation of verbal output. Machine-learning models combined these features to estimate chronological age and generate an individual speech age gap.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A large study shows that machine-learning clocks based on speech can estimate chronological age and may also offer a window into brain aging, biological aging, cognitive health, cumulative burden, and dementia.
