Ok guys, you MUST SEE THIS.
A Voctro's interview that shows some of the projects these guys are working. The guys are doing amazing things in the area of voice synthesis and manipulation. Tools that allows to transform the voice totally in something different, or use your voice as a control (for example for play a synthesizer instrument just singing). The second half of the video talks about Vocaloid . And the best, it's in English
I hope you enjoy it =)
