User blog comment:Vocaloids4life/Miyako: my own original vocaloid/@comment-25577599-20150517181944

If you mean an UTAU, that's about the only thing you can just "make" a VOCALOID for free with, on your own. Unfortunately, you'd need to a) be a company and b) have the approval of YAMAHA to even make a VOCALOID in the first place. It's a big deal, and not just something anyone on the Internet can make. Unless it's just a hoax, or a joke, or meant to be an UTAUloid, instead. ^ ^;
