Feminism

You're right, but this article points out present-day women are still being coached to slow down, lower the pitch of their voices, and prevent being described as "shrill", despite advancements in technology.

I see this article as a half-and-half argument on gender biases in speech and on the way audio / broadcast technology still leans toward male voices, even with theoretically solved problems.

For example, the frequency response of lots of microphones still boost higher frequencies which may cause a "shrill" sounding female voice, even though the transmission medium can theoretically broadcast that voice losslessly (but still don't, for bandwidth's sake). This can be solved with a bit of AV sound engineering, but the article points out how limited this time & budget is.

I have personal experience with this - Taylor swifts voice transmitted via industry standard Bluetooth SBC codec is shrill to the point of pain for me in every car I've tried. A quick switch to a different Bluetooth codec or to an aux cable solves all problems for me.
