The only way I know to do it is manually, which is gone over in the tutorial you reference.Essentially you create your own face-key animation. But I have had problems just animating the face from one expression to another. I find it works best to put a "neutral" face key in between each viseme. So my process is this: Load up M4 or V4 in Daz, and go to the pose and animate tab.. Give yourself plenty of keyframes in the timeline to work with, depending on how many visemes you want for the avatar.
Go to the scene tab and highlight the avatar "head". The go to the parameters tab and highlight Morphs/expressions. This gives you access to the visemes. Make sure they are all set at zero. Then, in the timeline click forward 3 frames (this is just what I do, you might need less, but this works for me). Then click on make a new keyframe. At that point, move the slider of your first viseme over where you want it. Click forward 3 more frames and make another keyframe there, and then reset the slider to zero. Click 3 more frames and make a new keyframe. Move the next viseme slider ...and so on repeating the process until you have all the visemes you want with a zero pose in between each one.
It's a long and tedious process as much of animation can be. Especially because M4 and V4 have a LOT of visemes. But I find I don't really need them all. There is an Iclone "order list" for their face-keys, but I can't remember where I saw it. Probably in the manual.
When you're done, export the avatar WITH animations of course. In 3dexchange, after you have converted the characters you will have access to the expression editor, where you can match up your M4 visemes with the Iclone phonemes.It takes some tweaking, they are not identical. You can also create custom expressions for your character for the face puppet tool, and set some other standard face movements.
I think some of this is covered in the tutorial you have, check that out for details.
Save your DAZ animation file, you might be able to use it on future versions of M4, since that is such a versatile avatar.
Good luck.
