How EXACTLY Does a CVVC Oto work?

Ok, CVVC for Japanese UTAU has been kinda popular lately and I want to know how the oto works so I can hop on the bandwagon. I heard that the VC part otos like a VCV, so I'm good with that, but the CV part.. How do you oto that without causing the consonants to double?

Oremo doesn't run on my computer, and I don't trust the auto-oto feature in Moresampler, so I oto by hand.
I have never used or worked with CVVC in my life, I personally prefer CV or VCV, but I want Shadow to be usable so I plan on doing a CVVC. Before you ask, as soon as I figure out how it works, I plan on making my own reclist.


How is a CVVC otoed? Also.... How do the USTs work for a CVVC?

In CVVC, you oto the CV parts as normal CV, and the VC parts are meant to be transitions. For example if you listen closely to a word like "koko", you'll notice that right at the moment it transitions as "ok" you can hear the "o" fade out in a way that only happens if the next consonant is a "k". The intended effect is not to double the consonant but to transition the end of the vowel more accurately. I don't have a CVVC otoing tutorial on me at the moment, but I know that Delta made one here.

CVVC is oto'd as such:

For vowels (you're familiar with VCV; the same transitional rules apply)...

- v.png
v v.png
v -.png


For - CV, VC, and CV...

- cv.png
v c.png - this applies to hard consonants (b, d, g, k, p, t)

v c - soft.png - this applies to fricatives, liquids, and nasals (ch, f, j, m, n/ng, r/l, s, sh, v, z, zh)

As for how to use CVVC in the context of a UST...
- Some people like to use presamp, which prevents having to directly convert the ust to a different format.

- Others prefer to use autocvvc to convert the ust to cvvc - I would say this is more full proof, esp. if you're working with a non-japanese bank and need control over transitions. The caveat is that you'll have a longer wait time for rendering.

Depending on the language, you may still need to edit things manually by hand.
