Japanese speakers
Mistake: Pronouncing it as "RIIDO ITTO" with a full d release and separated syllables.
Why: Katakana English preserves each syllable and doesn't easily flap d between vowels.
Fix: The d of "read" becomes a flap between the two vowels (like in "eat it"): [ˈriːɾɪt]. This flap-d is essentially indistinguishable from the flap-t. Same pronunciation as "reed it" or "read it" — one word.
Korean speakers
Mistake: Producing clear [d] and syllable break.
Why: Korean releases word-final consonants clearly.
Fix: In American English, both t and d flap between vowels — they become the same short tap: [ˈriːɾɪt]. British RP keeps them distinct but still links smoothly.
Spanish speakers
Mistake: Producing Spanish-style fricative [ð] between vowels for the d.
Why: Spanish d weakens to [ð] between vowels.
Fix: English d in this position flaps (not fricative): [ˈriːɾɪt]. Quick tongue tap, no sustained contact.
