I forgot to describe the purpose of the test pages:
the idea is to record the default language (and other language related
options of the AT such as the option to switch between dialects in a
base language, as noted by David Poehlman), then to open each of the
test files and make a note of the language (possibly language variant)
that you hear.
The goal is to check whether there is a language switch if the language
of the page is different from the AT's default language and the
language attribute uses an additional subtag.

I am especially intested in older AT versions that are still commonly

I had not checked which languages NVDA supported, so thanks for pointing this
out. I'll test NVDA one of the next days.

Thanks. I've only used the default settings in JAWS (except for the
synthesizer language), so I'll delve deeper into the other options.

Best regards,
