From Wikipedia:
Vocaloid (ボーカロイド Bōkaroido?) is a singing voice synthesizer. Its signal processing part was developed through a joint research project led by Kenmochi Hideki at the Pompeu Fabra University in Barcelona, Catalonia, Spain.

The software is intended for professional musicians as well as light computer music users and has so far sold on the idea that the only limits are the users' own skills.
