It is also known as Xamicoco or Xamacoco, although the tribe itself prefers the name Ishír (which is also spelled Ɨshɨr, Ishiro, Yshyr) and sometimes Jewyo.
Chamacoco speakers live in the northeastern part of the Chaco Boreal at the origin of the Río Verde in Paraguay.
[4] Four dialects of Chamacoco have been identified: Héiwo, in the Fuerte Olimpo area; Ebidóso and Hório, spoken in the Bahía Negra region; and Tomaráho, in the Alto Paraná Atlantic forests.

This project is being curated in close collaboration with Ɨshɨr language activists such as Andres Ozuna Ortiz.
