Dovahzul course on Memrise

I was doing the Memrise course and realized that it's not totally complete - there are some words that don't have an audio for it, so I can't practice how to speak them.

Will it be updated soon? And I searched for a possible Duolingo course, could someone tell me if it's happening or why it won't work? Finally, one question that does not fit the title: what's going on with legacy dovahzul (non-canon)?
