Beyond Dyadic Memory: Interaction-Aware Multimodal Memory with Adaptive Agentic Retrieval for Multi-Party Spoken Conversations

Wenxu Jia, Xize Cheng, Zihan Zhang +5

Long-term memory enables agents to accumulate information and reason across sessions, yet existing research primarily focuses on dyadic text or image-text conversations, leaving lo…

Vox-Infinity: Benchmarking the Limits of Long-Context Spoken Language Models

Xize Cheng, Wenxu Jia, Chenyuhao Wen +4

Long-context understanding remains a fundamental challenge for large language models, as excessively long inputs often lead models to forget salient information. This issue is even…
