Vocaloid 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, in 2000 (the same team that later founded Voctro Labs) and originally was not intended to be a full commercial project. Backed by the Yamaha Corporation, it developed the software into the commercial product "Vocaloid".
