It’s crazy how similar they are, especially the kh sound (example: [Funny liverpool accent of this amazing girl – YouTube](https://www.youtube.com/watch?v=sWAUrHODRWM) , or here where they use the Bern äwä [https://youtu.be/ndz86gVm71Y](https://youtu.be/ndz86gVm71Y))
Do you know other english accents that are this close to Swiss German?
