Direct Translation between Sign Languages
Sign language translation has made substantial progress between sign and spoken languages, while translation across sign languages remains less explored. Translating directly between sign languages could support communication across signing communities without requiring a shared written language. A cascade of sign-to-text, spoken-language translation, and text-to-sign models offers one route, but can propagate intermediate errors and requires three sequential translation stages. We develop direct sign-to-sign translation, whose training is limited by the scarcity of parallel signing across languages. To address this obstacle, we adapt back-translation to construct cross-lingual pairs from...
