I studied German in college, primarily due to some German-speaking ancestry. I wanted to be able to read the records of early family in the Moravian archives. Enjoyed it, did a summer in Trier. German is guttural when non-native speakers speak it. The language can be beautiful in the right circumstance, spoken by the right voice. We have a stereotype arising from WWII movies, with actors barking orders. That sounds guttural. But, there’s another language that sounds even worse when barking orders. It’s gotten less notoriety due to the comparative difficulty in learning it, I suppose. That would be Japanese.
I've long noticed that Japanese (in movies, anyway) sounds very guttural. That doesn't really make sense; Japanese doesn't look like a guttural language when transliterated.
Interestingly, the same Japanese doesn't sound guttural at all when the speaker is female.
