For about $300 a new software can sing any song you want. Vocaloid sings like a soul diva but can be programmed to sound even like Eminem. "We have cracked the genome of the English singing voice," says Ed Stratton, the president of Zero-G.
Using 2500 phonemes at four different pitches, Vocaloid solves the problem of synthesising human voice that has the widest range of transitions between sounds. When a song is loaded it takes the proper transitions from its database and combines them.
Vocaloid will be mostly used for automatic backing vocals as it is said to be too early to replace a lead singer, but Julius Smith of the Stanford University Center for Computer Research in Music and Acoustics says this approach went much further.
