AMUSE: Audio-Visual Benchmark and Alignment Framework for Agentic Multi-Speaker Understanding

Summary

The AMUSE framework introduces a novel benchmark for evaluating multi-speaker understanding in audio-visual contexts, addressing the limitations of current multimodal large language models (MLLMs) like GPT-4 in agentic reasoning tasks. It emphasizes the need for models to effectively track speaker roles and ground events over time, which are crucial for applications such as conversational video assistants. The framework evaluates models across various task families and modes, revealing significant weaknesses in existing models' multi-speaker reasoning capabilities. To enhance performance, the RAFT alignment framework is proposed, integrating reward optimization with multimodal self-evaluation, leading to substantial improvements in accuracy on the benchmark.
