You could record yourself just talking in response to one of my podcast episodes. Or another idea is you could start doing your own podcast like Zdenek from Zdenek's English podcast, which you might already know about. So that means not like reading from a transcript but just making something up yourself as you go along. And I suggest that you don't write it down first. Just think about the topic for a few minutes and then just start talking about it. You can get an idea of similarities or differences between yours, your speaking and my speaking. But also you can track improvements that you're making in your speaking as well.
