Is it possible to tag languages in an already-created PDF? I need the screen reader to differentiate between two different languages.
Set the main document language, File > Properties > Advanced tab > Language drop-down box under Reading Options. For text elements in a different language use the language property of the individual tags. That is, in the Tags panel, right click the specific tag, select Properties and set the Language property on the Tag tab. If a snippet of German is in the middle of a paragraph in English, for example, you can use a Span tag for the German text.
Hope this helps.

That did it. Thanks a lot!
