I've found spaced repetition a great way to increase the size of my vocabulary whilst learning a language. You're right that it's unnatural, but a large unnaturally-learned vocabulary can then be polished by practice in more natural contents, and I feel like the net result is more efficient than using the natural contexts alone. This is especially true since I do not have easy access to native speakers for half an hour every day, but I can practice with the Anki app whilst on public transport during that time.

Last time I learned a language (German), a small vocabulary was my perpetual weakness. Now I'm learning a different language (Spanish) with a different approach that makes heavy use of spaced repetition, and vocabulary is no longer my weakest point. Instead, listening comprehension is now my weakness. But with a decent vocabulary, I am now working on improving the listening comprehension using podcasts. If my vocabulary were weaker, this would be much more difficult as I would need access to a native speaker who would considerately restrict themselves to mostly use vocabulary I know.

One thing that’s helped a lot with my listening comprehension is following along in a printed book with an audiobook reader. Especially when it’s a translation of a story I already know, I can usually more or less follow the plot and let the language information seep into my unconscious.

Thanks for the tip! That's one thing that hadn't occurred to me to try. I've tried the same thing with TV/movies, but the subtitles are usually not identical to the spoken dialog - they tend to be simplified and paraphrased to be shorter - but eBooks should be very faithful to their written counterparts.
