Meet the Aheadform F1: a half humanoid robot designed for more realistic social interaction. It can switch identities, so you can use something like this as a teacher, therapist, and companion. These were recently working on teaching realistic lip motions to face robots. As they explain:
we used a self-supervised learning pipeline based on a variational autoencoder (VAE) combined with a facial action transformer, enabling the robot to autonomously infer more realistic lip trajectories directly from speech audio.Â
