This collection contains supplements to reference grammars and texts that are archived at Deep Blue Documents and at Zenodo. The supplements include lexical spreadsheets (xlsx and/or csv) and audio files (some of the audio recordings are transcribed in the grammars or text collections). The initial materials are from Tiefo-N and Tiefo-D. Supplements from other languages (Viemo, Siamou) are in progress and may be added later. These languages are thought to constitute their own branches of Niger-Congo, and in the case of Siamou even that affiliation is contested. Supplements from Jalkunan (a Mande language of SW Burkina Faso) are in a separate collection.
