English(EN) When Models Hear What They Expect: Diagnosing Prosodic Heuristics in Multimodal Sarcasm Detection

多模态大语言模型依赖讽刺启发式方法，而非真正的韵律

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-31 03:34

研究人员调查了多模态大语言模型（MLLMs）如何处理语音和文本，特别是关注讽刺检测。他们使用Qwen2.5-Omni和Qwen3-Omni进行的实验显示，添加音频输入实际上增加了假阳性，而没有提高真阳性检测。模型似乎依赖于一种刻板的、具有表现力的韵律启发式方法，其特点是音高升高和不规则停顿，而不是标记讽刺的真正韵律线索。在Gemini 3 Flash Preview中也观察到了这种启发式方法，这表明它是不同多模态大语言模型架构中普遍存在的问题。 AI

影响多模态大语言模型可能需要进一步完善，才能准确解读韵律线索，以完成讽刺检测等细微任务。

当模型听到它们期望的内容：多模态讽刺检测中的韵律启发式诊断

Multimodal Large Language Models (MLLMs) process speech and text jointly, yet whether they exploit prosodic cues for pragmatic inference or rely on surface acoustic patterns has received little systematic investigation. We address this through sarcasm detection, evaluating Qwen2.…
