Japanese speakers
Mistake: Pronouncing it as "HERUPU ASU" with epenthetic vowel and full [ʌ] onset for "us".
Why: Katakana English inserts vowels after each consonant.
Fix: The [lp] cluster ends in a released p that links to [ʌs]: [ˈhɛlˈpʌs]. Say "helpus" as one prosodic unit. No katakana vowel between l and p.
Korean speakers
Mistake: Producing aspirated [pʰ] and glottal reset before "us".
Why: Korean prosody adds glottal onsets and ㅍ carries aspiration.
Fix: Keep the p light and link directly to "us": [ˈhɛlˈpʌs]. English word-final p before vowel is usually unaspirated and links smoothly.
Spanish speakers
Mistake: Producing Spanish light l, or elongating vowels.
Why: Spanish l is light; Spanish stress patterns differ.
Fix: English l in "help" is dark [ɫ] (or lightly darkened before p). [ˈhɛlˈpʌs] with quick p-to-vowel linking.
