Hi @andrew199 thanks for your interest in Audio2Face.
Making good M, P, B shapes are sometimes difficult depending on the emotion states. We’re working towards providing a better deep learning network in future releases.
In the meantime, the general tips would be like this
As in the video, use some symmetry constraints if the lip shape is not symmetric.
If lip is not closing properly, try using lipOpenOffset in the post-process to close the lips. (attached image)
Neutral emotion tends to give good MBP poses, so use strong neutral emotion and a bit of other emotions.
