Oof. That might be a bit on the nose.The first time I encountered a Scottish accent for dwarves was in World of Warcraft back before it was an MMO. I admit I do the psuedo-Scottish accent nowadays, but before the game came out I would just do a bit deeper voice than normal.
According to Atlas Obscura based on Tolkien, dwarves should have sounded Arabic or Hebrew. Elves should have been Finnish or Welsh.
