Claire Bowern of Anggarrgoon (and a frequent LH commenter when she isn’t as busy as she apparently is these days) has joined Quentin Atkinson and Russell Gray in creating the North American English Dialect Survey:
We are doing research on different accents in American English. We know that Americans and Canadians have a great deal in common in the way they speak, but there are also differences. In order to study the ways that North American accents differ, we have put together a survey of common words, and we’d like you to participate!
As Mark Liberman says at the Log post where I learned about it, “All you need is an internet-connected computer with a microphone and a web browser that can run Flash. [...] This is a great idea, and I certainly encourage participation.” As do I.
