I’m learning a new language now after moving to a new country and found duolingo was difficult to follow due to the artificial voice.
Memrise has been great though, not only are the voices natural, the app shows a video of a native speaker speaking a new word.
I highly recommend Memrise (so far) for learning a language. The format just clicks for me.
Edit: I will try this out when I get to my computer. Anything to help me learn my new language :-)
