Ear-Popping Artificial Singer by Deep Learning!
This is my first Hitfilm project (a music video). The song is in Japanese, but don't back off, just listen...
You'll be amazed how well it works -- an incredibly realistic vocal, almost *indistinguishable* from a real human singer!
Now get ready with your melody (midi notes) and lyrics: she starts singing for you! (and it's FREE!)
Oops, sorry -- it's only for Japanese songs right now, but there's no reason to believe that the technology won't apply to English or any other languages.
... which means, of course, you can get the Academy best song even if you don't have the budget for Celine Dion or Lady Gaga! :-)
