[libreoffice-accessibility] Conveying the language of document text

Hi all!

I was just playing with the latest Master dev build of LibreOffice 4.3 
again, and thought it would be nice if it exposed the language of text 
in a way that NVDA and other screen readers could use. If the currently 
active synthesizer supports it, text in multilingual documents would 
then be read with a voice/language appropriate. So English text would be 
read with an English voice, German text with a German one, etc.

In MS Office, at least JAWS and NVDA support that. The language is 
derived from the info about which language is set for spell checking 
that particular text. Since that information is available in 
LibreOffice, too, if the dictionaries are installed, it should be 
possible to expose that information.

Firefox does this in IAccessible2, and I've described it here: 
http://www.marcozehe.de/2008/07/17/support-for-text-attributes-and-spell-checking-is-coming-in-firefox-31/
Yes, that article is almost 6 years old, but still very much valid. ;-)

So far, I have not seen evidence that LO (or OO for that matter) expose 
the language portion of this info mentioned in the blog post. Or am I 
missing something?

Would like to check here first before filing an enhancement request.

Thanks!

marco
