In the future, our phone contacts will store name, address, phone number, voice model. (The messed up part will be that the user doesn’t necessarily send their model, but the model could be crafted from previous calls)

You could probably also transmit a low res grayscale version of the video to “map” any local reproduction to. Kinda like how a low resolution image could be reasonably reproduced if an artist knew who the subject was.
