The project 'Tongues of the Semang' documenting endangered languages and indigenous knowledge among foragers of the Malay Peninsula’ was launched in 2005. The aim of the project is three-fold: 1. to survey the current linguistic situation of the Semang communities, providing an assessment of their relationships and degree of endangerment 2. to document and describe the grammar and lexicon of Lanoh, a highly endangered and so far unstudied language spoken by some 360 Semang in the Perak Valley, Peninsular Malaysia 3. to study and document in-depth aspects of indigenous biological knowledge among the Jahai, a language community of about 1,000 Semang in Perak and Kelantan, Peninsular Malaysia.
This collection is also held in The Language Archive, Max Planck Institute for Psycholinguistics https://archive.mpi.nl.
