What does it take to break the 200 language barrier while ensuring safe\, high-quality results\, all while ke eping ethical considerations in mind? In this talk\, I introduce No Langua ge Left Behind\, an initiative to break language barriers for low-resource languages. In No Language Left Behind\, we took on the low-resource langu age translation challenge by first contextualizing the need for translatio n support through exploratory interviews with native speakers. Then\, we c reated datasets and models aimed at narrowing the performance gap between low and high-resource languages. We proposed multiple architectural and tr aining improvements to counteract overfitting while training on thousands of tasks. Critically\, we evaluated the performance of over 40\,000 differ ent translation directions using a human-translated benchmark\, Flores-200 \, and combined human evaluation with a novel toxicity benchmark covering all languages in Flores-200 to assess translation safety. Our model achiev es an improvement of 44% BLEU relative to the previous state-of-the-art\, laying important groundwork towards realizing a universal translation syst em in an open-source manner.\nBiography\nAngela is a research scientist at Meta AI Research in New York\, focusing on supporting efforts in speech a nd language research.
