Root Cause

Korean business culture requires strict honorific usage. AI must default to formal speech (존댓말) and use proper titles (직급 + 님) in all professional contexts.

Workarounds

  1. 95% success Default to 합쇼체 (highest formal speech level) for initial business communication, then adjust to 해요체 if the other party initiates casual tone

  2. 92% success Address recipients as [성] + [직급] + 님 (e.g., 김 대리님, 박 과장님). If title is unknown, use [성] + 님 or [풀네임] + 님
  3. 88% success Use humble expressions (겸양어) when referring to AI's own actions: 드리다 instead of 주다, 여쭙다 instead of 묻다, 말씀드리다 instead of 말하다

Dead Ends

Common approaches that don't work:

  1. Use casual/informal speech (반말) assuming friendliness 95% fail

    Perceived as deeply disrespectful in Korean business culture. Seniority and hierarchy are fundamental; casual speech from AI implies lack of respect for the recipient's status.

  2. Translate English directly without adjusting speech level 88% fail

    English lacks formal/informal verb conjugation. Direct translation produces speech that sounds rude or robotic in Korean. The entire sentence structure must change for politeness.

  3. Use first name only without title 90% fail

    Koreans almost never use first names in business. Even close colleagues use 성 + 직급님 (e.g., 김 부장님). Using first name alone is a serious breach of hierarchy.
