Potioncat:
Is it the same difference between pin and pen? We Southerners will 
insist upon asking for an ink pen because if we ask for a pen we 
might get a pin. (I grew up pronouncing get as git.)  Although my 
Yankee(as in Northerner) husband tells me that I pronounce pen and 
pin differently and properly, I cannot hear the difference. 

Now after all this, it's back to the buffalo. If Seamus and Ron and 
Hagrid and Draco all have different accents, how do they manage the 
spells? Or does it work just fine so long as they each pronounce 
accio consistently within their own speech patterns?

(Had to work canon in here somehow.)
