This paper introduces SPELL, a novel framework for active speaker detection (ASD) in videos with multiple speakers. It’s a complex task that requires learning effective audiovisual features and spatial-temporal correlations over long temporal windows. The proposed approach uses spatial-temporal graph learning to reduce ASD to a node classification task. This allows the model to reason over long temporal contexts without relying on computationally expensive fully connected graph neural networks. Experimental results on the AVA-ActiveSpeaker dataset show that SPELL outperforms all previous state-of-the-art approaches while requiring significantly lower memory and computational resources.

This paper creates a new way to find who’s talking in videos with many people. It’s like trying to figure out who’s speaking when there are lots of voices in a crowded room! The new method, called SPELL, uses special connections between different parts of the video to help it understand who’s saying what. This makes it much better at finding the person talking than other methods that use more complicated ways to analyze the video. And the best part is that it doesn’t need as many computer resources or memory to work.
