SubscribeAs for "uptalk," that is neither a regional phenomenon nor a new one. Cynthia McLemore and others have been investigating final rises among young American women for more than a decade and a half now (see here and here for further discussion). Most trace the intonational pattern to "Valley Girl English" as popularized by the likes of Moon Unit Zappa in the early '80s, though it probably could be detected among speakers from southern California long before that. Some of the other phonetic characteristics that Horowitz is gesturing towards also probably have a Californian provenance, particularly the shifting and lengthening of vowels as studied by Penelope Eckert. The popularization of like as a quotative or discourse marker has also been traced to California English.
