Visemes okay to use in facial pose set?

Are visemes acceptable in facial pose sets? I am assuming (?) these come free with daz studio, so if I want to use an EE pose for example to make the mouth form a pose this is acceptable to save as a pose preset?
Comments
they may be acceptable but whether it is good practice is another matter
for static poses it is less of an issue but a series of poses tweened in an animation with lipsync it could cause conflicts, not saying will and the likelihood of someone using any in an animation is slim but still something to bear in mind.
I myself dislike pose sets that radically alter visemes and yes have encountered some, I sometimes tween two poses for a facial closeup with lipsync or Mimic and indeed use expression poses to remove any deadpan looks.
Interesting. Well, I'm really only focused on static poses for now but I really appreciate your expertise on animation angle.
The visemes oftem make better expressions than the expressions do.
I am finding these to be true as they are less extreme. I have picked up facial poses which use visemes but have not delved into it yet. Posing the mouth differently using the dials is somewhat limited. Frankly I can’t get much movement out of the tongue as it doesn’t cooperate much at all though I have tried. So using visemes seemed an interesting option
The tongue is so important but every time I've tried to use it, well just once really, it's looked awful; e.g. the cop or waitress writing a ticket some people touch the tip of the pen or pencil to their tongue before they start writing but it just didn't look like a tongue. It was a bit to red, not bumpy enough, and those sorts of things.
most tongue poses seem to centre around licking and sucking things
like a lollipop?
Heh heh. I was trying for the lick lips or typical tongue out while performing a task kinda thing. I have not given up, but I wonder if I have a morph which is preventing it from going out far enough to be seen!
What I managed would of worked for a Charms sucker.
