Japanese speakers
Mistake: Pronouncing it as "HOORUDO ON" with a full d release and separated syllables.
Why: Katakana English preserves each letter; d-elision at cluster boundaries is unfamiliar.
Fix: The d of "hold" elides before the vowel of "on" — actually the l links directly: [ˈhoʊˈlɒn] or in slower speech [ˈhoʊldˈɒn]. The dark l [ɫ] links into [ɒ].
Korean speakers
Mistake: Producing clear released [d] and glottal reset before "on".
Why: Korean prosody adds glottal onsets to word-initial vowels.
Fix: The l of "hold" links directly to the [ɒ] of "on": [ˈhoʊˈlɒn]. If the d is preserved, it comes before the l→vowel bridge: [ˈhoʊldˈɒn]. Both are natural.
Spanish speakers
Mistake: Producing light Spanish l and glottal reset.
Why: Spanish l is light; Spanish prosody may add breaks.
Fix: English l in "hold" is dark [ɫ] — hollow, back-of-mouth quality. Link directly to [ɒ]: [ˈhoʊˈlɒn]. Say it as one word, no gap.
