International Translation Day examines the two-way shaping of language and AI

September 30 is the UN-recognized International Translation Day. The European Commission holds a virtual event today under the theme 'Languages unite! How languages shape inclusion,' with discussion of language across lifelong inclusion and parallel sessions on how languages shape AI and AI shapes languages, plus quality guidance for translation traineeships. Language technology can expand cross-language communication and production, but sparse data for low-resource languages, missing evaluation, error propagation and lost cultural context can also deepen inequality. Today's event establishes an agenda and practice-guidance direction, not language equity in deployed models. Next measures include training-data coverage, language-specific evaluation, professional review and access in public services.
