In general Language specialities should be accents.  The only people
without accents as specialities are:

* Excellent speakers of the language who have worked to remove their accent.
* Very poor speakers of the language who mostly know stuff in a
  topical area (viz a normal specialization).
* People who've learned a language entirely academically without using
  it on natives.  (They might have an entirely inappropriate accent
  specialization; but in general they'll be assumed to have an accent
  related to their native tongue).
  
Various different dialects are inter-understandable.  The table below
gives modifiers for understanding.  If not listed below two dialects of the same 
language are at -1.  The table is far from complete...
