Slow German podcasts - really good tool for beginners and intermediates http://www.slowgerman.com/
I've been listening to these in the car lately and have found it has really helped my listening skills. They are around a B1/ B2 level (she also does some absolute beginner podcasts).
These are slow read daily newscasts and completely free :)
This is great! I've been listening to the "normal" speed and then listening to the slow speed and trying to transcribe as its spoken. Aiming to do 1 article per day.
This link is great, because you can read the page and listen to the reading at the same time.
I tried to improve my listening skills with the easy German video interviews on YouTube but they spoke oh so quickly. I didn't know slow German speaking podcast were available. Cheers will look into it.
