Incident 1446: KBS AI Translation Subtitles Reportedly Broadcast Profanity During Artemis II Launch Livestream

Description: During a live broadcast of NASA's Artemis II launch, KBS reportedly used AI-generated real-time translation subtitles that reportedly mistranslated aviation terms including "roger," "roll," and "pitch" into Korean profanity. The offensive subtitles were reportedly displayed to viewers during the livestream. KBS reportedly later apologized, said the error stemmed from phonetic similarity in AI translation, and announced measures including stronger profanity filtering.

Variants

A "variant" is an AI incident similar to a known case—it has the same causes, harms, and AI system. Instead of listing it separately, we group it under the first reported incident. Unlike other incidents, variants do not need to have been reported outside the AIID. Learn more from the research paper.
