📝 摘要（中文）

尽管近期的视觉-语言-动作（VLA）模型已开始融入音频，但通常将声音视为静态的执行提示或仅关注人类语言。这导致在任务执行过程中，环境声响的瞬时变化未能得到有效利用，造成关键声音的遗漏。为了解决这一问题，本文提出了视觉-声音-语言-动作（VSLA）连续控制范式，并引入HEAR框架，整合了流媒体历史记录器、适应全感知输入的推理模型、音频世界模型以及流匹配策略生成器。通过构建OpenX-Sound进行预训练，并推出HEAR-Bench基准，本文展示了声音中心操控的因果持续性和显式时间学习的重要性。

🔬 方法详解

问题定义：本文旨在解决在任务执行过程中，环境声响的瞬时变化未能得到有效利用的问题。现有方法在音频处理上存在延迟和静态性，导致关键声音的遗漏。

核心思路：提出视觉-声音-语言-动作（VSLA）范式，强调连续的听觉意识，设计HEAR框架以整合多种感知输入，提升实时操控能力。

技术框架：HEAR框架包括四个主要模块：流媒体历史记录器（Historizer）、适应全感知输入的推理模型（Envisioner）、音频世界模型（Advancer）和流匹配策略生成器（Realizer），共同实现声音中心的操控。

关键创新：HEAR框架的创新在于将音频视为动态输入，强调因果持续性和时间学习，区别于传统的静态音频处理方法。

关键设计：框架中采用了流媒体历史记录器以保持音频上下文，推理模型基于全感知输入进行多模态推理，音频世界模型通过预测未来音频代码学习时间动态，流匹配策略生成器则确保动作的平滑性。

📄 摘要（原文）

While recent Vision-Language-Action (VLA) models have begun to incorporate audio, they typically treat sound as static pre-execution prompts or focus exclusively on human speech. This leaves a significant gap in real-time, sound-centric manipulation where fleeting environmental acoustics provide critical state verification during task execution. Consequently, key sounds are easily missed due to low-frequency updates or system latency. This problem is exacerbated by action chunking with open-loop execution, which creates a Blind Execution Interval where acoustic events are lost between discrete audio observation windows. Recognizing the necessity of continuous auditory awareness, we formalize Vision-Sound-Language-Action (VSLA) as a continuous control paradigm conditioned on vision, streaming audio, language, and proprioception under delayed decision loops. As an instantiation, we introduce HEAR, a VSLA framework integrating four components: (i) a streaming Historizer to maintain a compact, causal audio context across execution gaps; (ii) an Envisioner adapted from omni foundation models to reason over multi-sensory inputs; (iii) an Advancer, formulated as an audio world model, to learn temporal dynamics by predicting near-future audio codes; and (iv) a flow-matching Realizer policy to generate smooth action chunks. To address the scarcity of pretraining data and evaluations for VSLA, we construct OpenX-Sound for pretraining, alongside HEAR-Bench, the first sound-centric manipulation benchmark with strict causal timing rules. Our results suggest that robust sound-centric manipulation necessitates causal persistence and explicit temporal learning. This framework provides a practical step toward multi-sensory foundation models for embodied agents, enabling robots to perceive and interact with dynamic environments.
