How do you supplement your learning with Duolingo?

I've really enjoyed Duolingo and I think it generally does a decent job exposing you to vocabulary words and grammar, but one thing I've found problematic is that, with recent updates, there is so much repetition I feel like I'm just memorizing what certain sentences and phrases look like as opposed to "hearing" and understanding them. This has made me further realize that, while I can generally read the language I am learning, I am abysmal at going from spoken word to understanding. Does anyone have some good tips on how to get more exposure to spoken word in the language you are learning or otherwise supplementing your Duolingo experience?
