AMUSE: Audio-Visual Benchmark and Alignment Framework for Agentic Multi-Speaker Understanding
This paper introduces AMUSE, a novel benchmark and RAFT, an alignment framework, designed to evaluate and improve agentic multi-speaker understanding in MLLMs. AMUSE features six challenging tasks across zero-shot, guided, and agentic modes, revealing current models' weaknesses in complex dialogue scenarios. RAFT, integrating reward optimization and selective parameter adaptation, achieves significant performance gains (up to 39.52% relative accuracy improvement) on the benchmark, offering a practical path for developing more robust and socially-aware multimodal agents.

AMUSE introduces six challenging audio-visual tasks (AVDS, AVSA, NSP, SRID, STG, CSNL) targeting agentic multi-speaker understanding, requiring planning, grounding, and reflection. It exposes weaknesses in current MLLMs across zero-shot, guided, and agentic evaluation modes.
RAFT (Reasoning-Acting-Feedback Training) is a data-efficient alignment strategy. It combines Reflective Reward Optimization (RRO) for intrinsic multimodal self-evaluation and Selective Reasoning Adaptation (SRA) for efficient parameter updates, leading to significant performance gains.
MLLMs perform poorly in multi-speaker reasoning without explicit guidance. RAFT significantly improves grounding accuracy, temporal consistency, and dialogue coherence. Open-source models like Qwen3-Omni, when fine-tuned with RAFT, achieve up to 39.52% relative accuracy improvement, often surpassing closed-source counterparts.

Impact of RAFT on Multi-Speaker Dialogue Summarization
Before RAFT, models frequently produced generic summaries, often failing to correctly attribute speaker roles or ground events in time. For instance, a model might summarize 'The president discussed immigration rules' without specifying 'the person in the red dress' said it between '5 and 40 sec'. With RAFT's Reflective Reward Optimization and Selective Reasoning Adaptation, models demonstrate a significant improvement in identifying the correct speaker, maintaining role continuity, and coherently summarizing multi-turn dialogues across specific temporal segments. This leads to summaries that are not only textually accurate but also perceptually grounded and socially consistent, achieving up to 54.54 BLEU@4 for AVDS task, a 48% relative improvement over prior methods.
