I used the handy audio pronunciation feature on my dictionary, and I am not a German speaker, but I can definitely see how that eggcorn might have occurred.

https://en.wikipedia.org/wiki/Eggcorn

> An eggcorn is the alteration of a word or phrase through the mishearing or reinterpretation of one or more of its elements, creating a new phrase which is plausible when used in the same context. Thus, an eggcorn is an unexpectedly fitting or creative malapropism. Eggcorns often arise as people attempt to make sense of a stock phrase that uses a term unfamiliar to them, as for example replacing "Alzheimer's disease" with "old-timers' disease", or William Shakespeare's "to the manner born" with "to the manor born". The autological word "eggcorn" is itself an eggcorn, derived from acorn.
