Lip Sync, Viseme (Diffeomorphic imported characters).
Blender (4.5) Lip Sync add-on declares the following Viseme:
sil
PP
FF
TH
DD
kk
CH
SS
nn
RR
aa
E
ih
oh
ou
UNK
but the Daz Visemes defined are:
AA
EE
EH
ER
FIH
IY
K
L
M
OW
S
SH
T
TH
UW
W
I couldn't help noticing there are 16 items in both cases. So two questions. (1) which visemes map to which in Blender and (2) is there an easy way to turn them into shape keys for use with Lip Sync.

This video teaches how to create visemes for the lipsync addon, so you can compare with the daz visemes and see what you need.
Yea I saw that Padone. I was hoping for a shortcut. I'm very lazy. Preferably something I can script so I don't have to go through it again and again. That reminds me... I wonder if it's possible for it to be added to Diffeo.... Hmmmmm...
NVM I found I can morph to shapekey in the setup tab, and select the Visemes. Then I can map them to more or less the correct values.
Yes that's what I meant, not that you have to do the shapekeys yourself, sorry I didn't notice you were asking for conversion. The daz visemes are included in FACS.
