To learn how technology can help save their languages, some tribes sent members to Las Vegas in February.
The article “To save endangered languages, tribes turn to tech“* gives few details about the meeting, but does briefly mention Cherokee (chr), Ho-Chunk (Winnebago (win)) and Pit River (Achumawi (acv)).
Also mentioned is Thornton Media, a company that has developed a number of apps and software programs for language revitalization. According to their PDF, they have apps released for 14 languages so far and are working on apps for 12 others.
