Korean pronunciation trips learners up in ways spelling does not warn you about. Hangul is written one way and read another once sound-change rules kick in, and several consonants come in threes that English speakers hear as one. Record yourself reading Korean and this checker tells you where you land. It writes out in Hangul what your speech sounded like, compares it with standard Seoul pronunciation, and gives word-level feedback on each error: a plain ㄷ where a tense ㄸ belongs, a final consonant you released or dropped, 합니다 read letter by letter instead of as [함니다], or ㅓ drifting toward ㅗ. It also comments on pitch and intonation across your phrases, marks which words came through clearly and which did not, and closes with targeted practice suggestions.
Example result
Input
A 30-second recording of an intermediate learner reading: 저는 한국어를 배우고 있습니다. 학교에서 친구를 만났어요.
Output
Heard as: [저는 한구거를 배우고 이씀니다. 학교에서 진구를 만나써요] Liaison: 한국어를 correctly linked as [한구거를]. Good. Nasalization: 있습니다 correctly nasalized to [이씀니다]. Tensing: 학교 should be [학꾜]. The second syllable came out plain, closer to [학교] read letter by letter. Aspiration: 친구 was heard as [진구]. The ㅊ needs a stronger puff of air; it is currently a plain ㅈ, which changes the word. Vowels: 저는 drifts toward [조는]. Keep the lips unrounded and relaxed for ㅓ. Intonation: natural rise and fall within phrases; the final 요 rises slightly, which sounds like a question. Practice: minimal pairs 자다 / 차다 / 짜다, and 거 / 고.

How it works
How Korean Pronunciation Checker works
- 01
Read or speak Korean
Sign in, open the checker and record a sentence, dialogue line or short passage, or upload a clip. Choose which AI model analyzes it.
- 02
Consonant triplets and batchim
The AI checks whether plain, tense and aspirated consonants stay distinct (달, 딸, 탈) and whether final consonants settle on the right one of the seven batchim sounds without an extra vowel.
- 03
Sound-change rules
It listens for liaison (연음), nasalization (비음화), tensing (경음화), aspiration with ㅎ and ㄹ assimilation, and shows in Hangul where your version differed from the expected pronunciation.
- 04
Vowels, pitch and a practice list
Finally it compares vowel pairs such as ㅓ/ㅗ and ㅡ/ㅜ, describes the pitch shape of your phrases, and lists the corrections that will help you most.
Use cases
Who it is for
Self-study learners
Check sentences from your textbook or app between lessons, and find out whether your tense and aspirated consonants are actually being heard as different sounds.
TOPIK and exchange-program candidates
Rehearse self-introductions and interview answers, and fix the sound changes that make read-aloud Korean sound stiff.
Heritage speakers
If you understand Korean well but grew up speaking it little, see which details, such as batchim or vowel contrasts, give away an accent.
K-drama and K-pop fans shadowing lines
Record yourself shadowing a scene or lyric and compare the Hangul transcription of your attempt with the original line.
Tips
Get better results
- Record a sentence you have the Hangul for, so you can compare the checker's transcription with what you meant to say.
- Pick practice text rich in batchim followed by ㄴ or ㅁ (먹는, 입니다) to exercise nasalization, which learners often skip.
- For consonant triplets, hold your hand in front of your mouth: aspirated sounds push air, tense sounds are tight with almost none.
- Speak at a natural pace. Slow, syllable-by-syllable reading blocks the linking and assimilation that native speech uses.
- Work on one flagged pattern for a week, then record the same passage again to see whether it moved.
Limitations
What it can't tell you
Feedback is an AI estimate from a single recording, compared against standard Seoul Korean. Regional dialects such as Gyeongsang or Jeolla, which use pitch and vowels differently, may be marked as errors even when they are natural for those speakers. The Hangul transcription reflects what the model heard and can itself contain mistakes, especially with noisy audio. It supports practice and does not replace a teacher or an official speaking exam score.
Frequently Asked Questions
Korean Pronunciation Checker questions
How can I check my Korean pronunciation?
Record yourself reading Korean text you know the spelling of, upload it, and the checker returns a Hangul transcription of what it heard alongside the expected form. Errors are explained word by word, from consonant type to sound-change rules, with suggestions for what to practice next.
Why are ㄱ, ㄲ and ㅋ so hard to tell apart?
English uses voicing (g vs k) to separate sounds, while Korean uses breath and tension. Plain ㄱ is lightly aspirated, tense ㄲ is tight with no puff of air, and aspirated ㅋ has a strong burst. Tense and aspirated consonants also tend to start the phrase on a higher pitch, which is a clue the checker listens for.
What are Korean sound-change rules?
They are regular ways letters change sound next to each other. Liaison moves a final consonant onto a following vowel (음악 is [으막]), nasalization turns ㅂ, ㄷ, ㄱ into ㅁ, ㄴ, ㅇ before a nasal (국물 is [궁물]), and tensing makes some consonants tense after certain batchim. The checker flags each one you missed.
How do I pronounce batchim correctly?
Final consonants in Korean collapse to seven sounds (ㄱ, ㄴ, ㄷ, ㄹ, ㅁ, ㅂ, ㅇ) and stops are unreleased, so 밥 ends with closed lips and no burst of air. Learners often add a small vowel after them. The report points out batchim you released, dropped or replaced.
Is this good for Korean speaking practice?
It is best for pronunciation practice: getting the sounds, linking and intonation right on sentences you choose. It does not hold a conversation or correct grammar and vocabulary. Pair it with a speaking partner or tutor, and use the checker to tidy up what you say.
What does using the checker require?
It is part of the AI toolset, so you need an account on a paid plan; each recording spends credits. Plan details are on the pricing page.
