I guess it depends on if you understand what you're listening to? Repetition helps if you're not understanding what you're listening to...or are having trouble making out the words being said. Repeating would help with matching the sound of the word to the German word and translation in your head.
I think it makes sense to do repeated listenings to shorter material (under ten minutes). A full audio book probably doesn't make sense unless you just want to listen to it again for pleasure. However, you could repeatedly listen to a chapter over and over if you want to really get it practice on it. In my opinion though, I think it may be best to move on at some point as you start to "memorize" the story. It would seem that it's then best to move on and try to encounter words in different contexts.
There can also be a difference in material you want to use strictly for entertainment vs. material to use for purposes of practicing.
I agree, I think what steve means by repeating is when you do not understand the words, when it ends and when the next one starts and all seems somehow fuzzy. But if you do understand then no need. and I have materials for repeated listening ( like mini stories) under 10 mins and others for pleasure of one time listeningSeptember 14 at 09:50
You are not quite right.
If you would like just understand what you are reading and really understand 80% of the text, you needn't repeat listening.
But if you really LEARN a new language and really want to remember the main words from the text, you need repeat listening and maybe even reading.September 14 at 13:44
