In the past two years, I have had the exact following conversation around 57 times:
Someone: Where are you from?
Me: I am originally from Germany, but …
Someone: Oh, from Germany?!! There is this really funny video on YouTube …
Me: [Sigh.] I know that one already.
Someone: … where they compare the sound of German …
Me: Yes, I know which one you mean. Everyone mentions that to me.
Someone: You have to watch it! It’s really funny!
Me: I have seen it often enough, thank you, and it’s really not that funny.
Someone: Kraaaaaankenwaaaaagen! [rolling with laughter]
Me: [being unimpressed/tired/annoyed]
You know which video I am talking about. It’s this silly stereotyped video which was not even particularly funny the first time I watched it.
I kept pointing out that German can actually sound quite agreeable when I speak it and that we aren’t really shouting and screaming all the time. Actually, after living in Malta and in Bari, I can say for certain that there are countries/regions where people shout much more. We can probably add some Middle Eastern and at least one North American country to that list.
Anyway, finally someone got around to making a more nuanced, neutral, scientific comparison between German and a few other languages:
Granted, comparing anything with Hungarian or Latvian skews the playing field a bit.
