A recent appeal from grad student Paul Reed:
I am a PhD candidate at the University of South Carolina. I am a sociophonetician, and my research focuses on varieties of American English in the Southern United States. My dissertation investigates the vowel and intonation systems of Appalachian English.
… I am working on a project with Dr. Stan Dubinsky and I am writing to see if you would be willing to take a few minutes to take some surveys to help facilitate our research (the links for which are included at the bottom of this post in no particular order). [details on Reed's Blogspot site, link above] The experiments that we’re asking you to participate in are part of a project aimed at finding out more about how the English language works, (in particular) examining how Modern American English is perceived. Each survey involves rating sound clips based on the acceptability of various sentences and should only take about 15 minutes to do.
I’m happy to pass this request on, but my main interest here is in the label Appalachian English.
