Batchim: how to pronounce Korean final consonants
A batchim is any consonant written underneath a Korean syllable, and the rule for all of them is the same: you close your mouth for it and stop. No puff of air, no little vowel afterward. English releases its final consonants, so "jip-uh" for 집 is the habit almost every English speaker brings in, and it is the first thing Korean listeners notice.
Seven sounds, many spellings
Korean writes a lot of different consonants in final position, but when a syllable ends there, only seven sounds survive: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ and ㅇ.
Everything else collapses into one of those seven. ㅅ, ㅆ, ㅈ, ㅊ, ㅌ and ㅎ at the end of a syllable are all pronounced as a stopped ㄷ, which is why 옷, 낮 and 꽃 all end the same way. ㅋ and ㄲ collapse to ㄱ, and ㅍ collapses to ㅂ.
So the spelling tells you what the word looks like and what happens when a vowel follows. It does not tell you what the syllable sounds like on its own. Learn the seven and you have learned every batchim there is.
Stopped, not released
This is the physical part, and it is one instruction: get into position for the consonant and stay there.
For 집, your lips close for the p and remain closed. You do not open them again. Say the English word "top" and freeze with your mouth shut at the end, resisting the urge to release — that frozen position is the Korean batchim.
For 책, the back of your tongue rises to the soft palate and stays. For 옷, the tongue tip presses the ridge behind your teeth and stays.
There is no puff of air, because a puff requires a release. And there is no vowel afterward, because a vowel requires opening the mouth. The sound ends with your articulators locked in place — the listener hears the closure, not the consonant coming out.
ㄴ, ㅁ and ㅇ are the exception in one sense: they are nasals, so sound keeps coming out through your nose while the mouth is sealed. But the mouth still does not reopen.
Why English speakers add the extra vowel
English releases nearly every final stop, often with an audible puff. "Cup", "back", "hat" — say them naturally and you will hear a small burst after the consonant. That burst is close enough to a tiny vowel that a Korean ear hears an extra syllable.
Korean is syllable-counted. Turning 집 into two beats does not just sound accented; it makes the word structurally wrong, in the same way that adding a syllable to an English word would.
There is a second, subtler version of the mistake: releasing without a vowel but with a puff. That still sounds wrong, and it is harder to catch in your own speech, because the puff feels like nothing from the inside. Recording catches it immediately.
Words to practice
Take one word per closure position and drill the stop. 집 for the lips, 책 for the back of the tongue, 옷 for the tongue tip. Say each one and freeze at the end for a full second. Only then relax.
Then the nasals, where the mouth seals but the sound continues: 밤, 산, 강. Hold the hum for a second so you can feel that nothing escapes through the mouth.
Then ㄹ: 물, 말, 달. This one is held rather than stopped — the tongue tip curls up to the ridge and stays in contact while the voice keeps running.
Then the spellings that collapse: 옷, 낮, 꽃, 있다. All of those end with the same stopped ㄷ sound despite four different letters. Say them in a row and confirm that the endings are identical.
What to listen for
Count the beats. Say 집 and count how many syllables came out. If it is two, the mouth reopened.
Listen at the very end of the recording. A correct batchim ends abruptly, almost as if the file were cut short. A released one has a small tail of noise after the consonant. That tail is the whole problem.
Then check what happens when the next syllable begins with a vowel, because the rule flips: 밥을 is pronounced 바블, with the batchim sliding onto the following vowel. Locking a batchim in place when it should be linking is the opposite error and just as audible.
In TonePerfect, batchim sounds are scored as their own units inside real Korean words, and your sounds come back ranked weakest-first — for most English speakers the final consonants sit near the bottom at first, and they are also the fastest to move. Those scores rank your own sounds against each other; they are not accuracy percentages or a TOPIK level, because no human-labeled Korean calibration exists to make numbers like that honest.

Questions
How many batchim sounds are there?+
Seven: ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ and ㅇ. Every other final spelling is pronounced as one of these when the syllable stands alone.
Why do 옷 and 꽃 sound the same at the end?+
Both ㅅ and ㅊ collapse to a stopped ㄷ in final position. The original spelling comes back when a vowel-initial ending follows, which is why the letters are still written.
What is a double batchim like ㄳ or ㄵ?+
Two consonants written under one syllable. On its own, only one of them is pronounced; the other reappears when a vowel follows. Which one survives depends on the pair, so learn them word by word.
Is ㅇ silent or is it "ng"?+
Both, depending on position. At the start of a syllable ㅇ is a silent placeholder that just holds the space before a vowel. As a batchim it is the "ng" of "song".
