Adding a pretrained facial-expression encoder to a voice activity projection model yields competitive or slightly better turn-taking prediction on the NoXi French subset, though the improvement is not statistically validated.
For SP and BC, our models (Proposed1 and Proposed3) outperformed the baselines, where the differ- ence lies in the use of facial embeddings from the pre-trained encoder

Voice Activity Projection Model with Multimodal Encoders
Adding a pretrained facial-expression encoder to a voice activity projection model yields competitive or slightly better turn-taking prediction on the NoXi French subset, though the improvement is not statistically validated.
