Voice-to-skull (V2K)
A claimed method of transmitting brain–computer interface data — signals sent to the brain — remotely and with no implanted device, such that a person perceives audible speech or sound inside the head with no external acoustic source. It describes the “write” (input) side of a BCI delivered at a distance: where cochlear and auditory brainstem implants create sound by directly stimulating neural tissue through surgically placed electrodes, V2K describes achieving a comparable internal perception wirelessly. Its proposed physical basis is the microwave auditory effect; claims of transmitting intelligible speech this way go beyond what that documented effect has established.
