For Arapaho, the population of native speakers of the language rooted in the Great Plains is aging. In an effort to fend off its disappearance, a team at the University of Colorado (CU) Boulder and the Northern Arapaho Language and Culture Commission are deploying digital tools including databases and language education projects. While the text database is unpublished, it has already underpinned important projects aiming to preserve Arapaho and make learning the language more accessible. One of the reasons that the full text database isn’t publicly available is the fear that it will be used or exploited by artificial intelligence. Nevertheless, 5,000 sentences approved by native Arapaho speakers will be published online.
