English pronunciation for Korean speakers

    Korean speakers' highest-impact fixes are /f/→/p/ ('coffee' → 'copi'), /z/→/dʒ/ ('zoo' → 'joo'), the r/l alternation, and the helper vowel that sneaks in after final consonants ('finish' → 'finishi').

    Stress and rhythm

    • Cut the helper vowel after finals: 'church', 'finish', 'orange' end on the consonant, not '-i'.
    • Korean intonation is flatter; mark stressed words with a clear pitch jump.
    • Statements need a decisive final fall; rising ends sound unsure.

    • Final-consonant discipline: whisper the ends of words with zero vowel after.

    Questions

    What are the hardest English sounds for Korean speakers?
    The highest-impact challenges are /f/ (no /f/ in korean); /z/ (/z/ becomes /dʒ/); /l/ (r and l are one korean sound in alternation). These are ordered by how much they affect intelligibility, not by how noticeable they are.
    Do Korean speakers need to lose their accent for IELTS?
    No. IELTS explicitly accepts every standard accent; the descriptors only mention L1 accent at Band 8, and only through its effect on intelligibility. The goal is clarity, not sounding native.
    Where should I start?
    f-drill in the mirror: teeth visibly on the bottom lip: coffee, office, before.
