Precisely, adding aria-describedby on any active element with a role, whether ARIA based or implicit like a standard form field or link, will be announced when tabbing to it. The aria-describedby attribute also accepts multiple ID references separated by spaces for non-contiguous messages, and since this sets the Description property in the Accessibility Tree, it doesn't interfere with the Name calculation.

This is much more useful than setting tabindex="0" on everything, because it is totally unobtrusive.
