Re: ARIA instructions in other languages

That would have been my starting point, but at the screenreader level.

When you say ‘default instructions’ I assume you mean the help read out by the screenreader based on the components role, rather than text embedded in the page?

In which case it must be at the AT level, so in whichever screenreader you’re using.
You’ll need a French language voice…
