Fix what slipped
Each word and sound gets a score out of 100. Work on the weakest one, then check again.
How to read the scores: they're built for comparison, not certification. A lower score on ㅓ than on ㅏ means ㅓ deserves your practice time; the numbers rank your sounds against each other and your past attempts against each other. The app doesn't guess what you said instead — it shows you where the score dropped, and gives you the mouth mechanics to fix it.
What the checker listens for in Korean
Batchim come first: Korean final consonants are cut off, not released, so 집 ends with sealed lips and no extra 'uh'. Then the vowel pairs English merges: ㅓ in 어머니 is an open 'uh' with flat lips, ㅗ is a rounded 'o'. And ㅡ in 그림 — 'oo' with the lips spread — has no English match at all.
ㄹ is the fourth: a quick tap between vowels, as in 노래, and a held 'l' at the end of a syllable. The checker scores what Koreans actually say, so 좋아요 is graded as 조아요, not letter by letter.
Checker or test: which to use
The checker takes your own text, so it is the tool for the line you need to say. The Korean pronunciation test gives you five guided words in about a minute, with your sounds ranked weakest first.
Scores run from 0 to 100 and rank your sounds against each other; they are not an exam grade. One honest note: plain versus tense consonants at the very start of a word cannot be graded reliably, so judge that contrast in the middle of words.
The sounds that decide your accent
Batchim — the cut-off endings
Korean final consonants are stopped, not released. 책 ends with the tongue closed as for 'k' — never 'k-uh'. 집 ends with sealed lips. 옷 ends in a stopped 't', and the spellings ㅅ ㅆ ㅈ ㅊ ㅌ ㅎ all end with that same stopped 't'. Releasing the puff, or adding a little vowel after, is the single most common habit English speakers carry in.
ㄹ batchim — the held 'l'
A final 'l' with the tongue tip curled up to touch the ridge behind the teeth — darker and longer than the tapped ㄹ between vowels. Hold the contact.
ㅇ batchim — the 'ng'
The 'ng' of 'song'. Back of the tongue closes against the soft palate; the sound hums through the nose. Only ever at the end of a syllable.
ㅓ vs ㅗ
ㅓ is an open 'uh/aw' — like the 'u' in 'cut' said with the mouth a bit more open, lips NOT rounded. ㅗ is a rounded 'o' as in 'go' but pure, no glide at the end. English merges both toward 'oh'; Korean keeps them as two different words (어 vs 오). The lips are the whole difference.
ㅡ — the vowel English lacks
Say 'oo' but SPREAD the lips flat as if smiling. The tongue stays high and back while the lips refuse to round. There is no English substitute — this one you have to build from scratch.
ㅢ — two beats in one
Start from ㅡ (the flat-lipped 'oo') and glide quickly to 'ee' — two beats squeezed into one. Only at the start of words like 의사; elsewhere it reduces to plain 'e' or 'ee'.
Scores rank your own sounds against each other so you know what to drill first. They are not an accuracy certificate and not an exam grade.
