Um… some youtube examples of people actually speaking this way? The only person I’ve heard that sounds anything like this explanation mp3 was some actress from before my parents were born, not something I associate with young women.
Languagelog had a post on this a while ago. Their conclusion? It’s not a new thing by any means, moderate use is unlikely to be damaging and there haven’t been enough studies with far-ranging enough populations to say whether it’s increased in the young female demographic.
My opinion? It’s a thing that people do and calling attention to it like this is just going to embarrass people who didn’t realize they’re doing it and encourage others to increase their use of it, just to annoy you.
My personal theory is that the increasing use of vocal fry was kind of natural counterpoint to uptalk, (which also is considered to have “valley talk” origins, though I kind of disagree). This is because rising intonation traditionally indicated uncertainty, so the vocal fry came into use more and more in order to counteract that. It strives create an illusion of authority.
Do you really think anyone consciously changes their speech pattern to seem more or less authoritative? When women fry the trailing end of their sentences, they sound like diffident teenagers with quaking knees reading a book report in front of the class.
I agree it’s related to uptalk, sans the BS psychoanalysis. It’s just what young girls do because a lot of other young girls do it. In 15 years it will be something else, and someone will be characterizing it as a function of their confidence (or lack thereof).
