Korean pronunciation: every sound, batchim and sound-change rule, with audio
Korean pronunciation is learnable because Hangul is phonetic: each letter stands for a sound. The hard parts for English speakers are the three-way consonant contrast (plain ㄱ, aspirated ㅋ, tense ㄲ), two vowels English lacks (ㅓ and ㅡ), a ㄹ that sits between r and l, unreleased final consonants (batchim), and sound-change rules that make 합니다 sound like 함니다.
- Most consonants come in three versions: plain (ㄱ), aspirated (ㅋ) and tense (ㄲ)
- ㅓ and ㅡ have no English match; ㅐ and ㅔ now sound the same
- Only 7 sounds can end a syllable, and they are held, never released
- Sound-change rules link, nasalize and tense letters across syllables

Korean vowels
Korean has seven basic vowel sounds in modern Seoul speech, written with ten basic letters plus the combinations built from them. Vowels are short and pure, with no English-style glides. Two of them, ㅓ and ㅡ, do not exist in English and are where most of the work is. A syllable that starts with a vowel is written with a silent ㅇ in front: 아, 어, 오.
The basic vowels
| Spelling | IPA | Sounds like (US English) | Examples — tap to hear |
|---|---|---|---|
| ㅏ (a) | /a/ | The a of "father", short. | 아이[ai] · child사과[saɡwa] · apple |
| ㅓ (eo) | /ʌ/ [ʌ̹ ~ ɔ̝] | Between the u of "cup" and the aw of "law": jaw open, lips relaxed, not pushed forward. Not an "o". Drill it → | 어머니[ʌmʌni] · mother서울[sʌul] · Seoul |
| ㅗ (o) | /o/ | The o of "go" without the w-glide: lips well rounded and pushed forward. | 오이[oi] · cucumber모자[modʑa] · hat |
| ㅜ (u) | /u/ | The "oo" of "food", short, lips rounded. | 우유[uju] · milk누나[nuna] · older sister (of a male) |
| ㅡ (eu) | /ɯ/ | Say "oo" but keep the lips flat and spread, as if smiling. The tongue stays high and back. Drill it → | 그림[kɯɾim] · picture음악[ɯmak̚] · music |
| ㅣ (i) | /i/ | The "ee" of "see", short. | 이[i] · tooth; two기차[kitɕʰa] · train |
| ㅐ, ㅔ (ae, e) | /e/ [e̞ ~ ɛ] | The e of "bed". Most speakers today say ㅐ and ㅔ the same; spelling and context tell them apart. Drill it → | 노래[noɾe] · song네[ne] · yes개[ke] · dog게[ke] · crab |
y-vowels and w-vowels
An extra stroke adds a y in front (ㅏ → ㅑ). Combining ㅗ or ㅜ with another vowel adds a w in front (ㅗ + ㅏ = ㅘ "wa").
| Spelling | IPA | Sounds like (US English) | Examples — tap to hear |
|---|---|---|---|
| ㅑ ㅕ ㅛ ㅠ (ya yeo yo yu) | /ja jʌ jo ju/ | A quick y before ㅏ, ㅓ, ㅗ, ㅜ. | 야구[jaɡu] · baseball여자[jʌdʑa] · woman요리[joɾi] · cooking |
| ㅒ ㅖ (yae, ye) | /je/ | "yeh". After a consonant ㅖ is usually just "e": 시계 is shi-ge. | 얘기[jeɡi] · talk; story예[je] · yes (polite)시계[ɕiɡe] · clock; watch |
| ㅘ (wa) | /wa/ | The "wa" of "wander", with an open a. | 과자[kwadʑa] · snack; cookie사과[saɡwa] · apple |
| ㅝ (wo) | /wʌ/ | A quick w into ㅓ — "wuh", not "woe". | 뭐[mwʌ] · what원[wʌn] · won (currency) |
| ㅙ ㅞ ㅚ (wae, we, oe) | /we/ | "weh", as in "wet". ㅚ was once a rounded front vowel; today almost everyone says it like ㅞ. | 왜[we] · why회사[hwesa] · company |
| ㅟ (wi) | /wi/ [ɥi] | The "wee" of "week", with the lips rounded tightly. | 귀[kɥi] · ear위[ɥi] · top; above |
| ㅢ (ui) | /ɰi/ | A flat-lipped ㅡ gliding fast into "ee". After a consonant it is just "ee" (희망 [히망]); as the particle "of" (의) it is usually "e". Drill it → | 의사[ɰisa] · doctor희망[히망] [çimaŋ] · hope |
Korean consonants: plain, aspirated and tense
English has two kinds of stops: voiced (b, d, g) and voiceless (p, t, k). Korean has three kinds, and none of them lines up exactly with English. Plain consonants (ㄱ ㄷ ㅂ ㅈ ㅅ) have a light puff at the start of a word and become voiced between vowels. Aspirated consonants (ㅋ ㅌ ㅍ ㅊ) have a strong puff. Tense consonants (ㄲ ㄸ ㅃ ㅉ ㅆ) have no puff at all and a tight throat.
Pitch helps too: in Seoul speech, a vowel after an aspirated or tense consonant starts higher than one after a plain consonant. That is one reason 달 (moon), 탈 (mask) and 딸 (daughter) sound distinct to Korean ears.
The three-way contrast
Hold your hand in front of your mouth: aspirated = a strong puff, plain = a little air, tense = none.
| Spelling | IPA | Sounds like (US English) | Examples — tap to hear |
|---|---|---|---|
| ㄱ (g/k) | /k/ [k ~ ɡ] | At the start of a word, a k with a light puff (lighter than English k); between vowels, a g. | 고기[koɡi] · meat가방[kabaŋ] · bag |
| ㅋ (k) | /kʰ/ | A strong English k with a big puff, as in "kite" said emphatically. | 코[kʰo] · nose커피[kʰʌpʰi] · coffee |
| ㄲ (kk) | /k͈/ | The k of "skin" (no puff), with a tense throat. | 꼭[k͈ok̚] · surely; definitely아까[ak͈a] · a moment ago |
| ㄷ (d/t) | /t/ [t ~ d] | A light t at the start of a word; a d between vowels. | 다리[taɾi] · leg; bridge바다[pada] · sea |
| ㅌ (t) | /tʰ/ | A strong English t with a big puff. | 타다[tʰada] · to ride토끼[tʰok͈i] · rabbit |
| ㄸ (tt) | /t͈/ | The t of "stop" (no puff), with a tense throat. | 딸[t͈al] · daughter또[t͈o] · again |
| ㅂ (b/p) | /p/ [p ~ b] | A light p at the start of a word; a b between vowels. | 바다[pada] · sea아버지[abʌdʑi] · father |
| ㅍ (p) | /pʰ/ | A strong English p with a big puff. | 피[pʰi] · blood풀[pʰul] · grass; glue |
| ㅃ (pp) | /p͈/ | The p of "spin" (no puff), with a tense throat. | 빵[p͈aŋ] · bread아빠[ap͈a] · dad |
| ㅈ (j) | /tɕ/ [tɕ ~ dʑ] | Between the ch of "chip" and the j of "jam", softer than both; a j between vowels. | 자다[tɕada] · to sleep아주[adʑu] · very |
| ㅊ (ch) | /tɕʰ/ | The ch of "chip" with a strong puff. | 차[tɕʰa] · car; tea기차[kitɕʰa] · train |
| ㅉ (jj) | /t͈ɕ/ | A tense, puff-less "tch". | 짜다[t͈ɕada] · to be salty가짜[kat͈ɕa] · fake |
| ㅅ (s) | /s/ [sʰ; ɕ before ㅣ] | A soft, breathy s. Before ㅣ and y-vowels it becomes "sh": 시 is "shi". Drill it → | 사람[saɾam] · person시간[ɕiɡan] · time; hour |
| ㅆ (ss) | /s͈/ | A sharp, tense s with no breathiness, like the s of "sea" said firmly. | 쌀[s͈al] · uncooked rice비싸다[pis͈ada] · to be expensive |
ㄴ, ㅁ, ㄹ, ㅇ and ㅎ
ㄹ and ㅇ each have two jobs, depending on where they sit in the syllable.
| Spelling | IPA | Sounds like (US English) | Examples — tap to hear |
|---|---|---|---|
| ㄴ (n), ㅁ (m) | /n/, /m/ | As in English. | 나무[namu] · tree마음[maɯm] · heart; mind |
| ㄹ (start of a syllable) | [ɾ] | One quick tap of the tongue tip — the tt of American "butter". Not an English r, and not a full l. Drill it → | 노래[noɾe] · song사랑[saɾaŋ] · love라면[ɾamjʌn] · ramen |
| ㄹ (end of a syllable), ㄹㄹ | [l] | An l, with the tongue tip held on the ridge behind the upper teeth. Double ㄹㄹ is a long l. Drill it → | 달[tal] · moon서울[sʌul] · Seoul빨리[p͈alli] · quickly |
| ㅇ (start of a syllable) | (silent) | A placeholder: the syllable starts with its vowel. | 아이[ai] · child오이[oi] · cucumber |
| ㅇ (end of a syllable) | [ŋ] | The ng of "song" — never followed by a g. | 방[paŋ] · room강[kaŋ] · river |
| ㅎ (h) | /h/ | The h of "hat". Between voiced sounds it often fades (전화 "phone" can sound like 저놔), and next to ㄱ ㄷ ㅂ ㅈ it aspirates them — see the rules below. | 하나[hana] · one전화[tɕʌnɦwa] · telephone |
Batchim: the 7 final consonant sounds
A batchim is the consonant at the bottom of a Hangul block, closing the syllable. Many letters can be written there, but only seven sounds can be pronounced there: ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅇ. Every other letter collapses into one of them — 옷 (clothes), 낮 (daytime) and 꽃 (flower) all end in the same [t̚].
The three stop finals [k̚ t̚ p̚] are unreleased: the mouth closes and stays closed, with no puff of air and no extra vowel. 밥 ends with the lips shut, not "bap!" and not "ba-puh".
Seven final sounds
| Spelling | IPA | Sounds like (US English) | Examples — tap to hear |
|---|---|---|---|
| ㄱ ㅋ ㄲ | [k̚] | The back of the tongue closes as for k, and stays closed — no release. | 국[kuk̚] · soup부엌[puʌk̚] · kitchen밖[pak̚] · outside |
| ㄴ | [n] | The n of "sun". | 산[san] · mountain눈[nun] · eye; snow |
| ㄷ ㅌ ㅅ ㅆ ㅈ ㅊ ㅎ | [t̚] | The tongue tip closes as for t, and stays there — no release. | 옷[ot̚] · clothes낮[nat̚] · daytime꽃[k͈ot̚] · flower |
| ㄹ | [l] | An l held with the tongue tip on the ridge behind the teeth. Drill it → | 물[mul] · water말[mal] · horse; words |
| ㅁ | [m] | The m of "him". | 밤[pam] · night; chestnut김치[kimtɕʰi] · kimchi |
| ㅂ ㅍ | [p̚] | The lips close as for p, and stay closed — no release. | 밥[pap̚] · rice; meal집[tɕip̚] · house앞[ap̚] · front |
| ㅇ | [ŋ] | The ng of "song". Drill it → | 방[paŋ] · room공[koŋ] · ball |

Sound-change rules: why Korean is not read letter by letter
When a batchim meets the next syllable, the two often change each other. Spelling keeps the original letters; pronunciation follows the rules below. They are not optional or casual — they are how standard Korean is spoken, and words read letter by letter sound wrong.
Linking (연음): the batchim moves over
When the next syllable starts with a silent ㅇ, the final consonant slides into that slot.
Nasalization: ㄱ ㄷ ㅂ → ㅇ ㄴ ㅁ before ㄴ or ㅁ
A stop final turns into the nasal made at the same place when ㄴ or ㅁ follows. This is why every 합니다 is said 함니다.
ㅎ aspiration: ㅎ + ㄱ ㄷ ㅂ ㅈ → ㅋ ㅌ ㅍ ㅊ
ㅎ next to a plain consonant (before or after it) merges with it into the aspirated version.
ㅎ dropping: final ㅎ disappears before a vowel
A ㅎ batchim followed by a vowel is not pronounced at all.
Tensing: plain → tense after a stop final
After a [k̚ t̚ p̚] final, a following ㄱ ㄷ ㅂ ㅅ ㅈ becomes ㄲ ㄸ ㅃ ㅆ ㅉ.
Liquidization: ㄴ + ㄹ or ㄹ + ㄴ → ㄹㄹ
When ㄴ and ㄹ meet, in either order, both become ㄹ: a long l.
Palatalization: ㄷ, ㅌ + 이 → ㅈ, ㅊ
A final ㄷ or ㅌ followed by 이 (or 히) is said as ㅈ or ㅊ.

The 8 mistakes English speakers make in Korean
- 1
Aspirating plain consonants
English p, t, k at the start of a word carry a strong puff — that is Korean ㅍ ㅌ ㅋ, not ㅂ ㄷ ㄱ. Said the English way, 불 (fire) becomes 풀 (grass). Keep plain consonants light, and let them voice between vowels.
불바다고기 - 2
Missing the tense consonants
ㄲ ㄸ ㅃ ㅉ ㅆ are not just "stronger" — they have no puff, a tight throat and a higher pitch on the vowel. Without them, 딸 (daughter) sounds like 달 (moon) and 쌀 (rice) like 살 (flesh).
딸쌀빵 - 3
Saying ㅓ like ㅗ
ㅓ is open with relaxed lips; ㅗ is rounded. English speakers hear both as "o". 서울 is seo-ul with an open ㅓ, not "so-ul". 벌 (bee) and 볼 (cheek) differ only here.
서울어머니벌 - 4
Rounding ㅡ into "oo"
ㅡ keeps the lips flat. Rounded, it becomes ㅜ: 들 (field) turns into 둘 (two). Smile slightly while you say it.
그림음악들 - 5
Using the English r or l for ㄹ
Between vowels ㄹ is a quick tap, like the tt in "butter"; at the end of a syllable it is an l. The English r — tongue curled back — never appears.
사랑노래물 - 6
Releasing batchim or adding a vowel
Final ㄱ ㄷ ㅂ close and stay closed. A puff ("bap!") or an extra vowel ("ba-puh", "ji-buh") adds a syllable that is not there.
밥집옷 - 7
Ignoring sound changes
Korean is not read letter by letter. 합니다 is [함니다], 감사합니다 is [감사함니다], 학교 is [학꾜], 같이 is [가치]. Reading the spelling literally is one of the clearest signs of a learner.
감사합니다학교같이 - 8
Stressing one syllable the English way
Standard Korean has no word stress: syllables are fairly even, and the melody belongs to the phrase. English speakers say "ba-NA-na" and "sa-RANG-hae-yo"; Korean gives each syllable similar weight.
바나나사랑해요
Minimal pairs: words that differ by one sound
Each pair differs in one sound — a consonant type, a vowel or a final consonant — and means something different. Listen to both, then say them. If you can hear and produce the difference, that contrast is under control.
Plain ㅂ (light air) versus aspirated ㅍ (strong puff).
Plain ㄷ versus tense ㄸ: no puff, tight throat, higher pitch.
Aspirated ㅊ (strong puff) versus tense ㅉ (no puff).
Breathy ㅅ versus sharp, tense ㅆ.
Open, unrounded ㅓ versus rounded ㅗ.
Flat-lipped ㅡ versus rounded ㅜ — same tongue, different lips.
Final ㄴ (tongue tip) versus final ㅇ (back of the tongue, "ng").
Final ㄹ (held l) versus final ㄴ (n).
A note on the score: the recorder scores each sound against the word you were asked to say, so an aspirated ㅍ in 불 shows up as a low score on that sound — but it cannot tell you which consonant you said instead. Use the audio to compare.
Now say the pairs — get a score for each word
Same free recorder, same daily limit. Feel for the puff of air, and watch your lips on the vowels.
불
Plain ㅂ: a light p with very little air, then a rounded "oo" and a held l.

Korean pronunciation FAQ
Is Korean pronunciation hard for English speakers?+
Hangul makes it easier than it looks: each letter has a consistent sound. The hard parts are specific — plain vs. aspirated vs. tense consonants, the vowels ㅓ and ㅡ, ㄹ, unreleased final consonants, and the sound-change rules between syllables.
Is Korean pronounced the way it is written?+
Letter by letter, yes — but across syllables, no. Rules like linking (음악 → [으막]), nasalization (합니다 → [함니다]) and tensing (학교 → [학꾜]) change how written letters are said. Learn the seven or so main rules and you can predict almost every word.
Is ㄱ a g or a k?+
Both, depending on position. At the start of a word it is a k with a light puff (김치 starts with [k]); between voiced sounds it becomes a g (고기 [koɡi]); at the end of a syllable it is an unreleased k. ㅋ, by contrast, always has a strong puff.
Is ㄹ an r or an l?+
Neither exactly. At the start of a syllable or between vowels it is a quick tap, like the tt in American "butter" (사랑). At the end of a syllable, and when doubled (빨리), it is an l. The English r is never used.
What is batchim?+
The consonant written at the bottom of a syllable block. Many letters can go there, but only seven sounds are pronounced: ㄱ ㄴ ㄷ ㄹ ㅁ ㅂ ㅇ. The stops are unreleased, and a batchim often moves to the next syllable or changes it through the sound-change rules.
Are ㅐ and ㅔ pronounced differently?+
Not for most speakers today. Both sound like the e of "bed", so 개 (dog) and 게 (crab) sound the same; context makes the meaning clear. Learn the spelling, but do not strain to make two sounds.
Does Korean have stress or tones?+
Standard Seoul Korean has no word stress and no lexical tones: syllables are fairly even, and pitch rises and falls over the phrase. Some regional dialects, such as Gyeongsang, use pitch to tell words apart.
Can I check my Korean pronunciation online for free?+
Yes — the recorder on this page. Say the word, and each word and each of its sounds gets a score out of 100, weakest first. It runs in your browser and needs no account; the TonePerfect app has the full course.
