If you're making stock music for music libraries, this becomes really beneficial.
OWN ALL THE RIGHTS: You own the full rights (performance, sound recording, etc.) to the vocal track created with the voice synth-don't have to make any deals with the vocalist and there are no additional copyrights you have to worry about. Compare this to having to re-record the vocals in a studio again.
if you've changed the melody or some of the the lyrics in your song, it's easy to update this in the voice synth editor and export the vocal track for your DAW. PRODUCTION FLEXIBILITY: Easy to change vocal melodies and words on-the-fly during production e.g. Don't have to schedule a recording with a singer at a studio. you could produce full songs on a laptop in a cafe using a voice synth + DAW software. PRODUCE ANYWHERE, ANYTIME: A voice synth enables you to produce a song anywhere, without the need to record vocals in a recording booth/studio e.g. But if you're producing a track where the vocals are processed/autotuned/robotic, voice synths like Vocaloid might be just what you need. I think a voice synth like Vocaloid can't replace a good human vocalist with a soulful voice-not yet anyway. Or Porter Robinson's hit-smash duet 'Sad Machine' with the vocaloid Avanna. You've probably heard of the vocaloid Miku Hatsune already, since she opened for Lady Gaga.
