2026-04-30

AI Summary

This work proposes a low-latency, highly robust real-time simultaneous interpretation system designed to eliminate language barriers at the 2025 Osaka World Expo. The system innovatively integrates a chunked input mechanism, context-aware translation, and a multi-engine machine translation fusion strategy, significantly reducing end-to-end latency while maintaining high translation quality. Developed through close collaboration with industry partners, the system has been fully integrated and deployed in multiple Expo scenarios, demonstrating its effectiveness in facilitating seamless multilingual communication in real-world environments.

Abstract

In line with the Global Communication Plan 2025, we have pursued the development of multilingual translation technologies to realize a language-barrier-free experience at Expo 2025 Osaka. Our work includes the advancement of simultaneous interpretation systems emphasizing high translation quality and low latency. Key achievements include chunk-based input segmentation, context-aware translation, and multi-engine machine translation technologies. Through demonstration deployments and collaboration with private companies, our technologies have led to real-world applications, with several services and systems showcased at Expo 2025 Osaka.
