Your voice may hold clues to your brain’s age
An October 27 NIH report describes a machine-learning study of speech recordings from 2,928 native Spanish speakers in five Latin American countries. Researchers examined patterns such as pitch, timing, and word choice. Differences between estimated speech age and actual age were associated with cognitive-test results and some biological markers. The study itself was published September 30; this week’s development is NIH’s report on it.
The appealing idea is a less expensive way to help researchers study brain aging. But a link found in today’s recordings does not prove the tool can predict someone’s future health. It needs longer-term testing and validation in other populations. This is not an approved diagnostic test, and asking a chatbot to judge your voice is no substitute for a clinical assessment. If changes in memory or speech are affecting daily life, bring them to your healthcare professional.
