Maybe. But if you image someone with a deep accent, only fundamental reading skills, spelling words by sound... if you read it out loud it almost sounds rural Kentucky, or Tennessee.

Although, I don't know how they came up with "gledding," unless that's how they learned it by hearing it. It's consistently wrong, and no amount of accent accounts for it.

Ooo! I now what it sounds like! Have you ever seen the parody YouTube series "Precious Plum?" It reads like someone with that accent spelling by how they say the words.
