Language Proficiency Fast Lane

Prep for TOEFL, IELTS, and the Duolingo English Test with speaking feedback that actually teaches

Koydo already covers broad test-prep needs, but the highest-intent language-test buyers need a tighter story: deadline-driven speaking practice, L1 interference coaching, and visible improvement they can trust before exam day.

Show the exact sounds that cost points on test day

This is the campaign asset the brief calls for: a fast visual that makes pronunciation coaching feel measurable, corrective, and urgent for learners with fixed exam dates.

Coaching Snapshot

✓

Move the tongue forward for /th/ instead of replacing it with /t/ or /s/.

✓

Round the vowel so the middle sound stays open and natural.

✓

Finish with a clean final /t/ release for clearer examiner intelligibility.

Why this converts

Learners do not just get a score. They see exactly which sound broke down, what to change, and how quickly the next attempt improves.
