Places you might look for data:

The Language Archive "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."

Also, the Endangered Languages Archive:
https://www.elararchive.org

There are also often archives for regions of interest, e.g., The Alaska Native Language Archive.

You usually have to register and agree to the terms of the archive to access the corpora.
