International Dialects of English Archive

This is a real actor dork thing, but I just love it so much.

Very simply, it's a website with recordings of English speakers, categorized by continent/country/state/region. In each, the person reads a standardized snippet that captures all of the sounds necessary to phonetically notate an accent or dialect, and then they do some talking about... whatever. Each file notes the year of the recording, the person's age, and details about where they've lived and other factors that account for regional influences.

It's a GODSEND for actors seeking examples of specific, realistic dialects, but also a super fun time machine and way to revisit the sounds of places you've lived, people you've loved, or the residents of some future adventure.
