Linguists have actually taken measures to study the famously unusual speech patterns of New York Times executive editor and noted dog-lover Jill Abramson. A video of Abramson talking, in case you’re unaware.
You’ll be shocked to know that scientists at Penn have found that Abramson’s speech differs from other people’s.
It’s quite common to see phrase-final low-pitched stretches in which alternate pitch periods start to vary systematically in amplitude. This can result in an abrupt apparent doubling in period (and a corresponding halving in fundamental frequency). A clinical variant of this is called “diplophonia”, but most people do it sometimes — it’s a natural consequence of oscillation in non-linear physical systems, and is a specific instance of the phenomenon of “period doubling” much loved by complexity buffs. I’ve sometimes seen period-tripling. But this is first time that I’ve ever seen such a large-factor amplitude modulation so stably superimposed on a speaker’s sequence of pitch pulses.
Science has spoken.
Also, if you’re into this kind of thing, here’s a podcast of Abramson talking about The Puppy Diaries.
