Contrast Drills
변별 연습. Train the sounds beginners confuse most.

Core pronunciation model
Beginner view. switch depending on how much detail you want.
Three consonant families
Korean stop sounds come in plain, airy, and tight versions. Do not collapse them into one English sound.
Read by blocks
Treat each square Hangul block as one beat of sound, not as separate letters in a row.
Batchim changes sound
A final consonant often sounds different from the same letter at the start of a syllable.
Use audio over spelling
Romanization helps at first, but your ears should become the final authority.
ㄱ / ㅋ / ㄲ
Beginners often hear these as just one “k” sound, but Korean distinguishes plain, aspirated, and tense stops.
Listen for: Airflow first: ㅋ has the strongest burst, ㄲ has the tightest sound, ㄱ is the plain middle value.
bul-go-gi
bulgogi
ㄱ plain
ko
nose
ㅋ aspirated
kkot
flower
ㄲ tense
ㅂ / ㅍ / ㅃ
This contrast changes word identity fast and is hard if you rely on English-style “b” and “p”.
Listen for: ㅍ pushes air out; ㅃ is tight and clipped; ㅂ is the plain series with little aspiration.
bul
fire
ㅂ plain
pul
grass
ㅍ aspirated
ppul
horn
ㅃ tense
ㅓ / ㅏ
These two open vowels are one of the most common beginner confusions.
Listen for: ㅏ is brighter and more forward; ㅓ is more central and unrounded.
eo-meo-ni
mother
ㅓ open central
a-i
child
ㅏ open front
ㅗ / ㅜ
Both are rounded, but one is higher and backer while the other sits slightly higher in the mouth.
Listen for: ㅗ is tighter and higher in the mouth; ㅜ is deeper and more “oo”-like.
o-i
cucumber
ㅗ
u-yu
milk
ㅜ
