Absolutely fascinating/terrifying (why do those always come in pairs with AI research?) but I think it's also interesting to use this to make some assumptions about how human brains work. When I hear a voice, I kinda have an idea what the person would look like. I can't really explain it, but there's definitely some assumptions I can make about age, weight – gender is easy but even within that, a deeper voice easily makes me think of more stereotypically male facial features. The model is also slightly racist (as we all are) so if I hear an Asian language, well, I might picture an Asian person.

So, basically, a lot of this stuff is actually likely happening right now in our brain. A lot of crazy complicated stuff, happening entirely subconsciously and never having been tested before because doing so empirically is somewhere between incredibly tedious and impossible.
