Fix first what changes the meaning
Priority is not pretty. Priority is “does this split two words?” In Korean that is often batchim (받침), the three-way stop contrast ㄱ/ㅋ/ㄲ, and 어 versus 오. When those collapse, people hear a different word before they hear an accent. Example: 불, 풀, and 뿔 are not a cute tongue twister. Order the wrong one and you have asked for grass or horn. Ten slow repetitions of the three, then the same three inside “불 주세요,” beat a night of drawing tongue diagrams for ㄹ. The other trap: polishing a sound that already works until the whole sentence stiffens. If people understand your 안녕하세요, take it off this month’s list. Spend the slot on the batchim that keeps disappearing at the end of 맛있어요.
Eight minutes: one sound, three sentences
A long pronunciation session becomes homework. Eight minutes is enough. • 2 minutes: pick today’s sound. Example: final ㅇ, or 가요 vs 가여. • 4 minutes: three sentences that carry it, slow then at living speed. • 2 minutes: one phone recording, original beside it if you have one. Same three lines Monday, Wednesday, Friday. Tuesday and Thursday: only the line you smeared. A new “minimum set” every morning is not minimum. On a train, mouth the shapes. Do the last two minutes out loud at home. Whisper-only weeks produce a whisper.
Recordings show rhythm, not just a guilty consonant
You cannot hear yourself while you speak. Play a native clip and your take back to back. Awkwardness usually lives in chopping and stress, not in the one letter you have been ashamed of since week two. Watch three things: where you speed up, where the pitch drops, which syllable gets the weight. A month spent hunting a perfect ㄹ while every sentence freezes is a common way to stall. Keep last week’s file. It is the only honest baseline. Skip the recording because it is embarrassing and “pronunciation practice” becomes another listening day.
Plant the set in a scene you will actually say
A clean sound that exists only at the desk is not a minimum set yet. Put it in one scene you will use: coffee, a hotel Wi-Fi password, “I have a reservation.” Failure case: forty minutes of pronunciation videos, mouth never opened. Knowledge rose. Muscle did not. Use a video only to pick three lines. Once a week, mark whether this week’s sound appeared in a real exchange. If it did not, the sentence was wrong — not the sound count. Change the scene line. Do not collect more IPA.
COMMON MISTAKES
Where a minimum set fails
Starting with the full vowel chart — the mouth closes. Polishing a sound that already works until the sentence stiffens. A new pronunciation video every day — shopping is not practice. No recording, only a feeling that it got better — no baseline. Believing ㄹ alone will make you fluent — batchim and 어/오 usually come first.
Today’s set is one sound and three sentences. A recording screen is handy; the phone’s voice memo is the same job.
