makes this sound like a new trend, Cliff Nass, who was studying computer voices back in the 1980s and 1990s, always stated that female voices were preferred, except in Japan, where male voices were considered to be more intelligent and authoritative.
Ironically, back in the '90s and the aughts, I preferred male voices, set very low in pitch, but in the past few years, I have preferred female voices. This might just be because female voice AI have become more pervasive, and thus become more integrated to "the voice in my head," which is what I call the kind of AI voice that becomes so quotidian as to be rendered unnoticed as something "other," something occurring outside of my own thoughts.

I was doing some searching to find out if Tom Hiddleston's voice was available as synthetic speech and, while that was sadly unsuccessful, I did find this, which makes me feel smarter every time I listen to it
