Podcasts in Esperanto/Esperantaj Podkastoj
As someone first began learning Esperanto back in 2010, I had a couple of podcasts that I would often listen to so as to help me learn to understand spoken Esperanto.
The first was Radio Verda/Green Radio. http://radioverda.com/
Unfortunately they aren't currently producing new podcasts, but you can still listen to the old ones. The speech isn't too slow or too fast and will greatly help you gain a feel for how the language sounds.
The other is Varsovia Vento/Warsaw Wind. They have a Facebook page, https://www.facebook.com/pages/Varsovia-Vento-Elsendoj/434973729901325 and they continue to produce new podcasts.
