>>11794684I know exactly how a northern accent sounds since I live here. A is closer to O, G is softer and pronounced more like a voiced Ch. Vowels are longer and consonants are dropped more often. What usually is pronounced F becomes a P, and AU becomes a long O while EI becomes a long I. Depending on how strong the accent is people say "dat" instead of "das", "watter" instead of "wasser", "better" instead of "besser", "et" instead of "es". "Ik" instead of "ich". "un" instead of "und", "anners" instead of "anders". "up" instead of "auf", "dien" instead of "dein".
It actually has more to do that the way people in the north speak is more archaic while the High German dialects have changed more over time.
