I get the idea of wanting to provide voiced communications for those that it may be difficult for (or for translation), but I still cannot rationalise why it needs to sound 'just like a real person.' Would the initiator feel silly if a service called for them and sounded robotic, rather than like a friend? Why does it need to distinctly act human? I cannot see the specific requirement for this imitation, other than it's cool/creepy. Or it's just tech marching on to deliver sci-fi dreams.
