“The Language Archive (TLA) is an integral part of the Max Planck Institute for Psycholinguistics in Nijmegen. It contains various types of materials, including: audio and video language corpus data from languages around the world; photographs, notes, experimental data, and other relevant information required to document and describe languages and how people use them; records of speech in everyday interactions in families and communities; naturalistic data from adult conversations from endangered and under-studied languages, and linguistic phenomena.”
