The future of performance may well indeed become even more fabricated than it is today. See the following clip ‘The Pieces Fit’ by Module. This music is more than a vocal with effects and a snazzy clip to match.
The female robot vocal is completely synthetic. It is done by using a generic text to speech website to generate the words and then the artist did a form of Audio motion capture by replacing the part he sang by matching up the waveforms.
Once that was done he put it through rewire in Melodyne and controlled it in real time via the midi keyboard recording it back into Ableton Live and then re-edited that performance for the most realistic emotional response.
Simple!! All in all, impressive stuff and a nod to the future of performance perhaps.
