This makes me wonder why they tried to make the voices sound gender neutral/other gendered rather than say, somewhat non human like. Would the supposed biases still be there if the voices were masked to sound like say, Darth Vader? Or maybe a Dalek from Doctor Who? Would there still be the same issues with speech patterns and what not if it sounded like the interviewee was speaking in robo speak?
