One feature of contemporary female speech in American English of the last few decades is the so-called ‘vocal fry’, defined as a vocal register “produced through a loose glottal closure which will permit air to bubble through slowly with a popping or rattling sound of a very low frequency.” Words uttered by mostly younger women at the end of clauses in this register have been characterized variously––and contradictorily–– as (1) producing greater credibility; or (2) making female speakers sound less confident, thereby undermining the effectiveness of their communication.
In light of several other cases (such as uptalk) that have been instanced in previous posts as characteristic of the speech of young women and girls in the 21st century, and explained as APOTROPAISMS, perhaps vocal fry should be categorized similarly, i. e., as a strategy used by speakers to avoid or forestall danger. More specifically, vocal fry could be likened to the behavior of an animal confronted by danger, including baring its teeth and/or claws, bristling, etc. The meaning communicated to her interlocutor(s) by a female speaker who resorts to the vocal fry is something like ‘don’t mess with me’. At a time when sexual harassment has become a staple of media discussions detailing the perils confronting American women in the 21st century, an explanation of vocal fry as an apotropaism gains special credence.
