{Korean} Why do they sound like this?
I was watching a show in Korean and I heard a girl pronounce the word "너" like "더" and the word "네" like "데"
and in another show I heard a guy say "비안해" instead of "미안해" and "붜?" instead of "뭐?"
Am I just hearing these words wrong or are they pronouned differently sometimes?

Answer

I also believe it's because words are pronounced more nasal. If you pronounce 네 nasally then it will sound like 데, similar with words starting with ㅁ sounding like ㅂ.

Answer

It's because we vibrate our vocal cords when pronouncing ㄴ/ㅁ. ㄴ/ㅁ is not pronounced exactly as 'n', 'm' in English.Pronounce ㄴ/ㅁ getting your vocal vords vibrating more.

Answer

Hi, this is not an answer in the first place. I just want to confirm that I've noticed the same thing as you:

ㄴ sounds like ㄷ
ㅁ sounds like ㅂ

Answer

"너" / "네" / "미안해" / "뭐" are right.
I guess when people speak Korean fast in usal life, It could sounds differently to foreigner.
I have same problem when I listen to English. I hear different pronounce.
