Korean punishes the mistakes AI loves to make: it mixes speech levels, sliding between formal and casual within a single exchange, and drops or misplaces the particles that carry meaning. The honorifics a native speaker chooses without thinking are exactly where the model slips.
Vietnamese is unforgiving of the small errors AI makes constantly: it drops or misplaces the tone diacritics that change a word entirely, and it stumbles over the pronoun system, where the right term depends on age and relationship.

Thai gives AI little room: words run together without spaces, tone carries meaning, and the politeness particles shift with who is speaking.
AI can string together grammatical Mandarin and still read as foreign: it fumbles measure words, reaches for stiff textbook phrasing, and drops idioms like chengyu at the wrong pitch.

Japanese exposes AI quickly: it mishandles keigo, mixing polite, humble, and honorific speech in ways that would embarrass a real speaker, and it fumbles counters and particles.
