Adding sounds to valyrian.
I really love the high valyrian course, but I do have a problem. I don't know how to properly pronounce the words, so I can't speak it. That kinda defeats the whole purpose of learning it.
I use Memrise for now until the "official" audio gets added to Duolingo. https://www.memrise.com/course/1586994/duolingo-high-valyrian-audio-wip/
Check out some stuff on YouTube for example. There are some videos of D.J. Peterson where he speaks HV. Another great thing are the Tutorials by Damien Halme, there you can also here a bit of HV. There is also a Discord server for HV so you can meet other people there and speak HV with them
