Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Older adults who have used multiple languages throughout their lives speak more clearly in both their first language and any additional languages they learned.

See the scientific wording

Greater multilingual experience is associated with enhanced speech quality in both native and non-native languages among older adults, suggesting that lifelong language use may support linguistic performance despite aging.

Why this might work

Speaking multiple languages over a lifetime strengthens the brain's speech circuits, making them more efficient and resistant to aging. This keeps speech clear even as the brain gets older.

  1. Study: Age-Related Differences in Speech and Gray Matter Volume: The Modulating Role of Multilingualism

    Older people who have spoken more than one language their whole lives tend to speak more clearly in both their first and second languages than those who only spoke one language — their brains also seem to age slower in areas that help with speaking.
