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.
Jalkunan is an endangered language of the Mande family, spoken in the village cluster of Blédougou in southwestern Burkina Faso. The lexical work complements a published grammar with texts. See the readme for further information.
The work on the Bangime language, spoken by the Bangande people, was carried out as part of a larger linguistic fieldwork project focused on Dogon languages. Bangime is confirmed as a language isolate with no demonstrable linguistic relatives—possibly the only such isolate in West Africa.
