This article deals with the technology to surreptitiously or overtly send "voices" to people. This is a longtime dream of psychological warfare and operations people, and much research and development has gone into it. Huge sums of money have been spent developing ways to send voices, in any and all ways, to targeted people. Many technologies are openly known to exist, and more sophisticated ones no doubt exist in secret. One name for this is synthetic telepathy; another is voice-to-skull (v2s) technology. I also discuss methods for sensing brainwaves and converting these to voice signals, i.e., brainwave-to-voice (b2v) devices.
