@garicgymro If they follow youtubers / twitch people, compare the phonetics of their speech now and some 5 years ago. Are there any interesting changes? Do people tend to move together, or are paths very different? Do they converge? Or do they build a brand?
(I'm thinking of people like Dunkey who really went through 2-3 accent phases in the course of their career, but I suspect it's a more broad phenomenon)
@garicgymro Or is it precisely, what you are looking for; a collection of good youtube videos? ;)
@garicgymro I have my little list from when I homeschooled my kids during covid, if it helps... Although I'm sure there are dozens of cool resources that appeared since then ; the pandemics was a real catalyst for cool online resources!
