I’m not sure about other languages in general, but in Korean females tend to use different intonations, pronounce vowels a little differently, and use different verb endings as a means of sounding more cute.
If you’re not familiar with Korean, then perhaps you’ve heard Japanese males speak before. They’re more harsh, sometimes gutteral, whereas females are more gentle when they speak.
I think I picked up the gentleness speech patterns, and I often catch people off guard. Firstly there’s a foreigner speaking Korean, but he also sounds like a hot chick 😂
