Omni-Embed-Audio: Leveraging Multimodal LLMs for Robust Audio-Text Retrieval

arXiv:2604.18360v2 Announce Type: replace-cross Abstract: Audio-text retrieval systems based on Contrastive Language-Audio Pretraining (CLAP) achieve strong performance on traditional benchmarks; however, these benchmarks rely on caption-style queries that differ substantially from real-world search behavior, limiting their assessment of practical retrieval robustness. We present Omni-Embed-Audio (OEA), a retrieval-oriented encoder leveraging multimodal LLMs with native audio understanding. To systematically evaluate robustness beyond caption-style queries, we introduce User-Intent Queries (UI

Why this matters
Why now

The rapid advancement and integration of multimodal AI necessitate robust retrieval systems that can handle real-world complexities beyond traditional benchmarks.

Why it’s important

Improving audio-text retrieval with multimodal LLMs directly addresses shortcomings in current AI understanding of complex user intent, enhancing the practical utility and robustness of AI applications.

What changes

AI systems will be better equipped to interpret diverse audio inputs and user queries, leading to more accurate and user-friendly voice assistants, search engines, and autonomous systems.
