I'm working my way through the Pimsleur German series, and I've noticed that one of the speakers has what seems to me a strange pronunciation of the word Milch.
He pronounces the ch like the sh sound in wish (in English), that is, the IPA sound ʃ. I would've thought it's pronounced like the IPA ç.
Is this common? Is it specific to certain areas of the German-speaking world? Or is it, in fact, the "correct" pronunciation?
