Turkish → English: the sounds that cost you points
The English sounds and patterns Turkish doesn't use — with mouth diagrams, minimal pairs, and drills.
Why this matters for your TOEFL Speaking score
Turkish is remarkably regular, so when English breaks Turkish rules — consonant clusters, "th", the /w/–/v/ split, voiced endings — your mouth resists. Those slips read as unclear words and quietly lower your Intelligibility construct. Fix a handful and your speech sharpens fast.
/w/ vs /v/ — west/vest, wine/vine
Turkish has /v/ but no /w/, so /w/ collapses into /v/.
The Turkish habit"west" → "vest", "wine" → "vine", "we" → "ve". The teeth touch the lip when they shouldn't.
The fix — /w/:round your lips like a small kiss, teeth touch nothing, then glide. /v/: top teeth on the lower lip, with a buzz.
vest ↔ westvine ↔ wineve → we
Drill (30s): exaggerate lip-rounding — w-w-w (no teeth) → we, want, wood, away. Then teeth-on-lip → very, vote, save.
/w/: rounded lips, no contact. /v/: top teeth meet the lower lip.
Construct: Intelligibility. west/vest, wine/vine, worse/verse are real word changes.
/θ/ and /ð/ — think, three, this
No "th" in Turkish — replaced by /t/, /d/ or /s/, /z/.
