Japanese speakers
Mistake: Pronouncing it as "HOTTO DOGGU" with a full t release and a separate strong onset for "dog".
Why: Katakana English preserves both consonants; "ホットドッグ" reinforces the two-word feel.
Fix: The t of "hot" is often elided before the d of "dog": [ˈhɒˈdɒɡ]. Or in slower speech, a held single stop covers both: [ˈhɒtˈdɒɡ]. Say "hoddog" — one word, one image (the food).
Korean speakers
Mistake: Producing a clear aspirated [t] and full onset [d] with syllable break.
Why: Korean prosody favors clear consonant boundaries.
Fix: The [t + d] cluster simplifies to a single stop: [ˈhɒˈdɒɡ]. As a lexicalized compound (a single food item), it's spoken as one prosodic unit.
Spanish speakers
Mistake: Producing a Spanish-style fricative [ð] for the middle sound, or over-articulating both consonants.
Why: Spanish d weakens between vowels; Spanish learners sometimes lose the stop quality entirely.
Fix: English d stays as a full stop: [ˈhɒˈdɒɡ]. The two consonants merge but neither weakens to a fricative.
