English pronunciation for Indonesian speakers

    Indonesian speakers most need audible word-endings: final stops are swallowed and clusters simplified, deleting the -s and -ed that carry English grammar. Then /v/→/f/, /z/→/s/, and the missing long/short vowel contrast.

    Stress and rhythm

    • Even 'machine-gun' rhythm is the main prosodic habit; pick one stressed word per phrase and compress the rest.
    • You already have a schwa (the e in 'besar'); recruit it for English unstressed syllables.
    • Finish words completely before starting the next; unclear endings compound across a sentence.

    • Long-vowel stretch: 'sheep, pool, food' held twice as long as feels natural.

    Words Indonesian speakers often get wrong

    Questions

    What are the hardest English sounds for Indonesian speakers?
    The highest-impact challenges are /t/ (final stops unreleased and clusters simplified); /z/ (/z/ devoices to /s/ or hardens to /dʒ/); /v/ (/v/ becomes /f/). These are ordered by how much they affect intelligibility, not by how noticeable they are.
    Do Indonesian 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?
    Endings bootcamp: over-pronounce -s/-ed for two weeks: 'workeD', 'planS', 'askeD'.
