When I compared accessibility APIs in the AEGIS project (roughly five
years ago), I did not see anything like language metadata - not in any
of the accessibility APIs that I looked at. So it seems that screen
readers cannot rely on the platform accessibility API to get the UI
language; they would need to get this information by other means,
possibly by parsing the DOM.

The mapping tables in the WAI-ARIA spec also don't list anything like UI

Best regards,
