Additionally I find even though I can understand an Indian accent for example quite well in person, I really struggle with it over the phone due to the compression causing quite poor sound quality and lack of facial expressions to be able to read (which I would be using in person to help me understand a strong unfamiliar accent), whereas when accent is more familiar to me, the poor audio quality and lack of body language isn't nearly as much of an issue, presumably as I just have way way more exposure to the accent so can fill in gaps better.
