currently being spoken in South America. However, 420 are seriously in danger of disappearing due to the
pressure of the majority languages and to the fact that the number of the speakers is very low. Although Brazil
is the country with the greatest linguistic variety in the region, it has the largest number of languages in danger
of extinction. Dr. Fábio Bonfim Duarte will present some results of the research that he has conducted in order to support activities of
documentation and revitalization of several of these languages. Such actions are urgent in the case of languages
like Aurê-Aura, Júma, Akúntsu, Avá-Canoeiro and Bará, which are spoken by less than 20 people.
