"Interested in regional and social differences in speech? We are too!"

Just got an email with that subject line for a study about how people identify speakers of different dialects:

Our research team at the University of Wisconsin is recruiting subjects for research on how people perceive and identify dialects of languages people speak. If you’d like to participate, just visit this link, and you’ll hear speech samples and can answer questions about them, e.g. where the speakers are from and whether you think they have strong accents.  The survey will not work on a smartphone; please only use a laptop, desktop, or tablet.
If you have any questions about the study, feel free to contact the study team by emailing jsalmons@wisc.edu. And you are welcome to contact us later if you would like to know about our findings as we learn more about the many ways our speech varies.

Could be fun.
