Yesterday afternoon, UC San Diego Linguistics grad student Amanda Ritchart presented her research (joint with Amalia Arvaniti) on the use and realization of uptalk in Southern California English at the 166th Acoustical Society of America meeting. This work is profiled in the ASA's press room, and has thus far received a fair amount of attention. You can hear and/or read about it on KPBS (San Diego's public radio station), at WBUR's Here & Now, on BBC News, and in the Washington Post. (See also this shout-out on the Linguistic Society of America website.)
Uptalk has been discussed many times here on Language Log, so regular readers are probably not unfamiliar with it. But one of the most recent Language Log posts on the topic ("Uptalk awakening", 9/29/2013) shows how relatively unaware of this long-standing feature of many varieties of English some folks still are. So the media coverage of Ritchart & Arvaniti's work is welcome — and on the whole pretty good, if a little biased toward a "wow, it's spreading to men!" interpretation of the research results, which kinda misses the point. But of course, if you scroll down to the comments (why oh why do I ever scroll down to the comments???), you'll see that many appear to think that the use of rising intonation at the ends of (some!) statements is the clearest evidence we have of the decline of western civilization. Sigh.
