Japanese speakers
Mistake: Pronouncing each word fully as "AZU SUUN AZU" with three separated words.
Why: Katakana English preserves each word and cannot easily s-link across boundaries.
Fix: The s's flow smoothly with connected s-linking: [əzˈsuːnəz]. The two "as" words reduce to [əz] with schwa. Say "əz-soon-əz" as one connected phrase.
Korean speakers
Mistake: Producing full [æz] for both "as" instances and clear syllable breaks.
Why: Korean prosody preserves boundaries and vowel qualities.
Fix: Both "as" instances reduce to [əz] in this construction: [əzˈsuːnəz]. Only "soon" carries stress. In fast speech may reduce further.
Spanish speakers
Mistake: Producing full [as] with pure Spanish vowel, or [z] as [s].
Why: Spanish has no [z] as a distinct phoneme; s often stays voiceless.
Fix: "As" uses voiced [z]: [əz]. And the vowel reduces to schwa in this unstressed comparison construction: [əzˈsuːnəz].
