C-3PO
The protocol droid from Star Wars
Fussy, clipped and mildly panicked — a very polite robot having a difficult day.
Darth Vader
Star Wars' central villain
Deep, flat, and mechanically calm — the villain read that works because it never raises its voice.
HAL 9000
The ship's computer in 2001: A Space Odyssey
Calm, level and completely unbothered — the polite computer voice that refuses your request.
