How can I tell the difference?!?!?!
When I hear Korean spoken, It's hard for me to tell the difference between;
ᄑ, ᄇ and ᄈ
ᄏ, ᄀ and ᄁ
ᄐ, ᄃ and ᄄ
ᄎ, ᄌ and ᄍ
ᄉ and ᄊ

Sometimes I can tell the difference between ᄏ andᄀ, ᄐ and ᄃ, ᄎ and ᄌ.
But I can NEVER tell the difference between ᄑ,ᄇ and ᄈ. ᄌ and ᄍ, ᄃ and ᄄ, ᄀ and ᄁ, ᄉ and ᄊ..

Is there like... anyway I can tell the difference? Like an easy way? T_T

Answer

You might understand ㄲ, ㄸ, ㅃ if you think how 'style', 'speak', 'sky' are pronounced in American English.

When ㄱ, ㄷ, ㅂ, ㅈ is NOT the first syllable of the word, they are pronounced as "voiced" sounds. Most Koreans are not aware of this fact because there's no concept of "voiced" and "unvoiced" sounds in Korean. 

See how the 아저씨 and 아줌마 pronounce those consonants.
