For me, it has to be Korean (Hangul is easy to grasp) but the pronounciation, my god: it’s like I can’t understand a word being said when they speak (while that part is manageable in listening to spoken Japanese). Maybe it’s just me not having the “trained” ear on listening to Korean phonology in real time whilst learning the language.
Spanish. Being a native ptbr speaker, a significant portion of Spanish can be more or less inferred, which is infinitely easier when reading rather than listening to. I don’t know if it’s me, but it feels like the only way to “properly speak” makes your voice sound “wrong”, whenever I hear someone who’s a native Spanish speaker, it sounds like they’re doing something weird with their voice.
I also hate how it is the only fucking language where J makes a throaty R sound
I wouldn’t call Spanish j an r, it’s more similar to German ch and Dutch g.
Heh-sus, Huh-an, Heh-remias, Hoh-achim
in Portuguese it’s the sound of rr, hence “throaty r”
TIL. Kinda sounds like Portuguese is the odd one out … but I guess that doesn’t help when you’re a native Portuguese speaker.
