Setup your face-rig

Next, go to "Rig Configuration" in the Auto-Lip-Sync area. Here you can define a pose for every phoneme. On the left, you can see the phoneme and an example word with that phoneme. Based on this information you can choose the pose of your face rig which best fits that phoneme. Note that for most face rigs you will use a pose several times.
