AILLA is a digital archive of recordings and texts in and about the indigenous languages of Latin America. Access to archive resources is free of charge. The heart of the collection is recordings of naturally-occurring discourse in a wide range of genres, including narratives, ceremonies, oratory, conversations, and songs. Many of these recordings are accompanied by transcriptions and translations in either Spanish, English, or Portuguese. These works contain a wealth of information about Latin American indigenous cultures as well as knowledge about the natural environments that the people live in. AILLA’s Links page has links to many indigenous organizations that are developing literature, publication, and education projects for their communities.
