A very neat project recently circulated / is circulating on The Internet about regional variations in pronunciation in the continental United States. (Thanks to Xtina for posting the link on my Facebook wall!)
Here’s the poster from the study:
The project reminded me of another study, this one about the term “bayou” in the US from 1954. Here’s a map from that article:
And that’s your serving of linguistic maps (over 50 years apart!) for today.
Data collection, aggregation, and cartographic depiction has probably gotten a lot easier since 1954, making the poster above (of various words and locations) possible (in contrast to the one word in roughly one region map below)! More on this when I summarize CHESS 2013 next week!
