Word lists

I’ve heard polyglots saying that learning languages using word lists is not such a good idea. I wanted to present a method ( which now is in the theory stage) in which you write new words in a list and then record them( either using your voice or the voice of a native speaker) and while reading the list you should also listen to them a couple of times.I also wanted to hear the opinions of the advanced language learners about this untested idea( though some may say that if it’s untested how could you know that it works).
