The pith

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

Omni-modal models can see, hear, and talk, but existing tests mostly check static answer accuracy. This paper argues that real conversational competence also requires knowing who is speaking, when to take a turn, and how to interrupt naturally. It introduces SocialOmni, a benchmark built around those three axes, with thousands of perception items, a controlled generation set, and audio-visual mismatch probes. Across twelve leading models, the scores vary widely by axis, and high accuracy on speaker identification often fails to line up with timely, appropriate interruptions. The result is a concrete case that understanding-centric metrics alone do not measure social interactivity, and that separate diagnostics are needed to close the perception-interaction gap.

Core claim

When twelve omni-modal models are scored jointly on speaker identification (who), turn-entry timing (when), and interruption generation (how), perceptual accuracy and generation quality systematically diverge: models that lead on who do not necessarily lead on how, and no model dominates all three axes. Controlled audio-visual inconsistency further exposes brittle cross-modal binding. The paper therefore claims that conversational social competence cannot be read off understanding accuracy alone.

What carries the argument

SocialOmni’s who–when–how evaluation: frame-level multiple-choice speaker attribution (with consistent vs inconsistent audio-visual clips), streaming turn-entry decisions scored by timing offset windows, and multi-judge scoring of generated interruptions.

Load-bearing premise

That a compact, tightly curated set of 209 generation clips with fixed one-second query steps, preset timing windows, and coarse three-judge scores is a reliable enough diagnostic of real-time social interactivity.

What would settle it

Re-run the same twelve models on a substantially larger, independently annotated generation set with human turn-boundary labels and human quality ratings; if perception and interruption quality then tightly co-rank, the claimed decoupling collapses.

Referee Report

4 major / 7 minor

Summary. The paper introduces SocialOmni, a benchmark for evaluating omni-modal large language models (OLMs) on audio-visual social interactivity along three axes: who (speaker identification via 2,000 MCQ perception items, including consistent/inconsistent AV splits), when (turn-entry timing on a 209-item generation set with signed offset categories), and how (natural interruption generation scored by three LLM judges on a {25,50,75,100} scale). Twelve commercial and open-source OLMs are evaluated under a dual-axis protocol with bootstrap CIs, macro-F1, E/O/L timing decompositions, precision–recall operating points, and consistency-gap diagnostics. The central empirical claim is a pronounced decoupling between perceptual accuracy and interruption-generation quality (e.g., Qwen3-Omni high who / low how; GPT-4o low who / stronger how), implying that understanding-centric metrics alone are insufficient to characterize conversational social competence.

Significance. If the decoupling result holds under stronger validation, SocialOmni fills a genuine gap: existing OLM suites (Table 1) largely measure static answer accuracy and do not jointly operationalize speaker attribution, turn-entry timing, and interruption realization under controlled AV conflict. The who design (orthogonal speaker/content distractors), Δ_cons robustness probe, and multi-judge generation protocol are concrete contributions, and the reported rank inversions and failure modes (saliency-driven attribution, premature silence-gap triggering, context–response decoupling) give actionable signals for architecture and training. Strengths include multi-model coverage, bootstrap CIs, macro-F1 against positional bias, and an appendix human check on a hard subset. The work is timely for full-duplex multi-party OLMs, provided the generation diagnostic is shown to be reliable enough to support the insufficiency claim.

major comments (4)
  1. The load-bearing claim of “pronounced decoupling” between who and how (§4.2, Table 2; Abstract; Conclusion) rests primarily on the N_g=209 generation split (§3.2, A.5) and the three-judge how protocol (§3.4, Algorithm 2, A.11). The paper itself keeps this set compact for variance control and does not report a full-benchmark human baseline or systematic human–judge correlation for how; A.17 gives human how only on a 50-item hard subset (55.15/100) selected from model failures. Rank inversions on this diagnostic are real, but without broader human calibration (or at least item-level agreement between judges and humans on a stratified sample of the 209), the inference that understanding-centric metrics are “insufficient to characterize conversational social competence” is stronger than the evidence currently warrants. Strengthen with human ratings on a larger, stratified generation sample a
  2. Limitations and A.10 acknowledge that Task II how scoring uses transcribed outputs and may underweight visual grounding and prosody. Yet the abstract and §5 frame how as “natural interruption generation” in an audio-visual social setting. If judges see only ASR + reference text, the how axis is effectively a text-continuation appropriateness score conditioned on a when decision, not a full multimodal social-response score. This weakens the claim that SocialOmni jointly evaluates the integrated who–when–how triad under multimodal cues. Either (i) make the text-only judging scope explicit in the main claims and title framing, or (ii) add a visually/prosodically grounded scoring condition (as partially sketched in A.10) and show that decoupling persists under that condition.
  3. When metrics depend on free parameters that are only partially stress-tested: streaming stride δ=1 s (A.6) and timing windows (θ1,θ2,θ3)=(1,2,5) s (A.7), with primary On-time defined as −1≤Δτ≤2 s. Table 4 and Figure 4–5 report useful E/O/L and P–R structure, and A.8 defines δ∈{0.2,0.5,1.0} binary metrics, but the main leaderboard (Table 2) and the “best when” ranking (Gemini 3 Pro Preview 67.31%) are not shown to be stable under threshold/stride sweeps in the main text. Because when is one of the three axes used to argue heterogeneous capability profiles and non-dominance (§4.2, Figure 3), report main-text sensitivity of On-time rates and model ranks to (θ,δ), or justify the windows with human timing-tolerance data rather than appendix-only rationale.
  4. Cross-task association is asserted as “pronounced decoupling” and “do not correlate” (§4.2) but is not quantified in the main results with a formal association statistic over the 12 models (e.g., Spearman ρ between who Acc and how score, with CI). Appendix A.16 defines correlation machinery largely for the hard-subset human analysis (A.17–A.18), not for the primary who–how claim. Add a model-level correlation (and optionally leave-one-out rank stability) between who and how on the full evaluation so the decoupling claim is a measured effect size, not only a pair of rank inversions.
minor comments (7)
  1. Table 1 and abstract claim “comprehensive” coverage; with 209 generation items this is better framed as a controlled diagnostic (as Limitations already does). Align abstract wording with Limitations to avoid overclaim.
  2. Figure 1(c) and Figure 3 are hard to read in grayscale; ensure distinct line styles/markers for the 12 models and define all radar axes (e.g., Robustness = 100−|Δ_cons|) in the caption.
  3. Inconsistent numbers: Table 5 lists OmniVinci overall Acc 15.15% while Table 2/3 list ~35.86%; VITA-1.5 Acc is 36.95 vs 36.97 in places. Reconcile perception tables and regenerate CIs if needed.
  4. A.11 defines large-gap as |s(a)−s(b)|≥20 while §3.4 uses ≥25 points for R_gap. Unify the threshold definition.
  5. Repeated wording artifacts (“consistent consistent,” “robust robust,” “systematically systematically”) appear in §3.3–3.4 and related work; a careful copy-edit pass is needed.
  6. MiniOmni2 is perception-only (*); state clearly in Table 2 caption that when/how means exclude it from cross-axis correlation analyses.
  7. Prompt cards (A.14) for when ask “Is it your turn to speak now?” while Algorithm 2 uses “Should Xi speak now?” with a designated speaker Xi. Clarify whether models are role-playing a fixed participant or answering about a named candidate, and keep prompts identical to the evaluation code.

Circularity Check

0 steps flagged

Empirical benchmark paper: who/when/how metrics and the decoupling claim are independently measured, not forced by definition or self-citation.

full rationale

SocialOmni is a benchmark-and-evaluation paper, not a first-principles derivation. Task I (who) uses top-1 accuracy and macro-F1 on 2,000 MCQs with fixed options; Task II (when) uses signed response offset Δτ and fixed timing windows (1, 2, 5)s; how uses multi-judge means on a discrete {25,50,75,100} scale. These quantities are defined independently of any model’s training objective and of each other, so rank inversions (e.g., Qwen3-Omni high who / low how; GPT-4o low who / strong how) are empirical observations, not tautologies. No parameter is fitted on a subset and then re-reported as a prediction of a closely related quantity. Self-citations in Related Work (video frame selection, RAG, quantization) are ordinary prior-work pointers and do not underwrite the decoupling claim or the benchmark construction. Limitations of the 209-item generation set and LLM judges affect validity/reliability, not circularity. No self-definitional loop, fitted-input-as-prediction, uniqueness import, or renaming of a known result as a forced derivation appears in the load-bearing chain.

Axiom & Free-Parameter Ledger

4 free parameters · 3 axioms · 2 invented entities

The central empirical claim rests on a small set of design choices that define what counts as correct social interactivity and how generation quality is scored. Timing windows, streaming stride, judge scale, and the curated generation subset size are free parameters chosen by the authors; the who–when–how triad and the reliability of LLM judges are domain assumptions. The benchmark itself is the main invented entity, with independent evidence only insofar as others can re-run it on the released data.

free parameters (4)
  • timing thresholds (θ1, θ2, θ3) = (1, 2, 5) s
    Define Interrupted / Perfect / Delayed / TooLate categories for the when-score; chosen by authors and justified only by appendix discussion, not derived from external theory.
  • streaming query stride δ = 1 s (with 0.5/2 s ablations)
    Controls temporal resolution of turn-entry decisions; selected as cost–precision trade-off.
  • LLM-judge discrete scale {25, 50, 75, 100}
    Coarse score set used for how; affects mean scores and large-gap rate.
  • generation subset size N_g = 209
    Kept small for annotation control; directly limits statistical power of when/how claims.
axioms (3)
  • domain assumption Social interactivity for OLMs is adequately captured by the joint who–when–how triad under multi-party AV dialogue.
    Stated as the operational definition in §1 and §3.3; other facets (prosody, gesture, multi-turn repair) are deferred.
  • domain assumption Three commercial/open LLM judges under fixed prompts are a sufficiently stable proxy for human judgments of interruption appropriateness.
    Used for all how scores (§3.4, A.11); only partial human calibration on a hard subset is provided.
  • domain assumption Clips with clear alternating turns and CC-BY-compatible multi-party dialogue are representative enough for diagnostic evaluation.
    Construction pipeline in §3.1–3.2; stricter selection for generation items is acknowledged.
invented entities (2)
  • SocialOmni benchmark (who/when/how tasks + AV-inconsistency split) no independent evidence
    purpose: Provide a unified interaction-oriented evaluation suite missing from prior OLM benchmarks.
    Defined entirely by this paper’s construction and metrics; independent evidence will come only from external re-use of the released data.
  • consistency gap Δ_cons = Acc_cons − Acc_incons no independent evidence
    purpose: Quantify reliance on visual–audio alignment for speaker identification.
    Paper-defined diagnostic; useful but not an external physical quantity.

Omni-modal large language models (OLMs) redefine human-machine interaction by natively integrating audio, vision, and text. However, existing OLM benchmarks remain anchored to static, accuracy-centric tasks, leaving a critical gap in assessing social interactivity, the fundamental capacity to navigate dynamic cues in natural dialogues. To this end, we propose SocialOmni, a comprehensive benchmark that operationalizes the evaluation of this conversational interactivity across three core dimensions: (i) speaker separation and identification (who is speaking), (ii) interruption timing control (when to interject), and (iii) natural interruption generation (how to phrase the interruption). SocialOmni 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. We benchmarked 12 leading OLMs, which uncovers significant variance in their social-interaction capabilities across models. Furthermore, our analysis reveals a pronounced decoupling between a model's perceptual accuracy and its ability to generate contextually appropriate interruptions, indicating that understanding-centric metrics alone are insufficient to characterize conversational social competence. More encouragingly, these diagnostics from SocialOmni yield actionable signals for bridging the perception-interaction divide in future OLMs.
