Abstract: Large audio-language models (LALMs) extend the large language models with
multimodal understanding in speech, audio, etc. While their performances on
speech and audio-processing tasks are extensively studied, their reasoning
abilities remain underexplored. Particularly, their multi-hop reasoning, the
ability to recall and integrate multiple facts, lacks systematic evaluation.
Existing benchmarks focus on general speech and audio-processing tasks,
conversational abilities, and fairness but overlook this aspect. To bridge this
gap, we introduce SAKURA, a benchmark assessing LALMs' multi-hop reasoning
based on speech and audio information. Results show that LALMs struggle to
integrate speech/audio representations for multi-hop reasoning, even when they
extract the relevant information correctly, highlighting a fundamental
challenge in multimodal reasoning. Our findings expose a critical limitation in
LALMs, offering insights and resources for future research.
