Source for dictation/ dictates

Hey there,
I am looking for a website/ app - source - where dictates in French (B2-C1) (and maybe English (C1-C2) are available. So far I could not find anything. Most of those websites who are offering dictates are just for beginners.
Maybe you can help me, thanks!:slight_smile:
