The International Dialects of English Archive is a collection of recordings of people speaking English from all over the world. It shows the distinct ways that mother tongue influences and regional influences can change the way a person speaks English. You can check it out here: https://www.dialectsarchive.com/
This site was very instructive for some of my trainees, back in the day. One of the best uses for it is to develop some idea of how the native speakers speak, so that there's less confusion when listening and trying to understand them.
For those who learn by doing and imitating, this is a great English speaking resource for you. :)
My favorite section is under Europe>Ireland. :D
