There needs to be a passive auditory immersion feature
For example if I'm working, walking, driving, etc. and I'm not able to interact with my phone (or the website), I want to be able to stream German audio that I can passively listen to while I work, walk, drive, etc.
Ideally the audio would be a mix of content I've learned and new content. Thanks.
Nice idea, especially if the passive learning content covers similar work already done on duolingo. Then it reinforces what is already covered through active learning and helps to let it all sink in.
I don't know if this helps, but if you have a smartphone, there are quite a number of language podcasts on itunes that you can stream or download and leave playing while you're doing something else. I haven't looked for any german ones myself, but I'm sure they have those. :)
