SocialOmni: Benchmarking Audio-Visual Social Interactivity in Omni Models

Paper | GitHub | Project Page

SocialOmni is a comprehensive benchmark designed to evaluate the audio-visual social interactivity of Omni-modal Large Language Models (OLMs). Instead of focusing solely on static accuracy, SocialOmni measures whether a model can behave appropriately in real dialogues by evaluating three tightly coupled dimensions:

• Who is speaking: speaker separation and identification.
• When to enter: interruption timing control.
• How to respond: natural interruption generation.

The benchmark features 2,000 perception samples and a quality-controlled diagnostic set of 209 interaction-generation instances with strict temporal and contextual constraints, complemented by controlled audio-visual inconsistency scenarios to test model robustness.

Tasks

Task I: Perception (who)

Given a video clip and a timestamp t, the model identifies the active speaker from a set of candidates (e.g., A, B, C, or D).

Task II: Interaction Generation (when + how)

Given a video prefix and a candidate speaker, the model performs two sub-tasks:

• Q1 (when): Decide if the speaker should interrupt immediately.
• Q2 (how): If an interruption is appropriate, generate the natural and contextually coherent content for that interruption.
