workflow to create blendshapes compatibles with accuface

Hi! I am wondering what is a good workflow to create blendshapes which are compatible to facial animate a character in iclone using accuface for a character created outside of character creator.

Is there a way to automatically create such visemes instead of doing everything by hand? I know about audio2face, which generates blendshapens automatically, however it doesn’t feel like a very nice program to use. Are there any alternatives?

Thank you!
