Learn the key points
| Plain letter | Doubled letter | With ㅏ |
|---|---|---|
| ㄱ | ㄲ | 가 ↔ 까 |
| ㄷ | ㄸ | 다 ↔ 따 |
| ㅂ | ㅃ | 바 ↔ 빠 |
| ㅅ | ㅆ | 사 ↔ 싸 |
| ㅈ | ㅉ | 자 ↔ 짜 |
Learn the written pairs first. Listen to each pair and try reading it. Do not treat a doubled letter as a rule to speak longer or louder.
How to make the sound
Try each sound briefly. These are starting cues, not an automatic pronunciation judgement.
가 · 까 / 다 · 따 / 바 · 빠
Use the same place of contact. For a tense consonant, begin with a firmer closure and release it compactly. Do not squeeze your throat or simply get louder.
사 · 싸
These are different sounds. Compare a firmer start for 싸 at the same friction area. Without a usable model, do not score sound discrimination.
