It would be amazing if there was audio for this. Regardless, this is so awesome and I am proud for the navajo people to get the recognition they deserve. Through genocide, persecution, and prejudice you have fought through it all and I am proud of you all. I am looking forward to learning the basics of your language (the language of the navajos, that is) :)
Yeah, if there's no audio, I'm not sure I want to continue. It is one of the most interesting sounding languages that I've ever heard; it's such a shame we can't hear it in Duolingo.
Usually when a language is added the audio is added later. I've been waiting on Swahili audio for a year. They finally have some.
