How does a cyborg, a man-machine sound? Legendary electronic band Kraftwerk tried to imagine it through their song of the same name. And if such a man-machine combination is what you need vocally, than you certainly should look for cyborg voices.
Cyborg or cybernetic organism is a being with both organic and biomechatronic body parts. is not the same thing as bionic, biorobot or android; it applies to an organism that has restored function or enhanced abilities due to the integration of some artificial component or technology that relies on some sort of feedback. While cyborgs are commonly thought of as mammals, including humans, they might also conceivably be any kind of organism. Yet, it is that combination of human and 'mechanic' that gives the main characteristic to what cyborg voices should sound like.
Development of enhanced human elements and artificial intelligence is accelerating not by day, but by minute, and any technical, or more general audience interested in the subjects will certainly react to cyborg voices. Of course, so will, a sciencefiction-or inted audience for feature films, documentaries, animations and particularly video games.
Essentially, a cyborg voice is mechanically generated human vocal. It can vome from a human and then be lectronically modified. Or it can be completely electronically generated and used to express original human thoughts, like in the case of late Dr. Stephen Hawking or another scientists that needed such a modulation, as did Dr.Peter Scott-Morgan. These vocal modulation can be more synthetic or more human, depending on the need and purpose.
