LLM-Augmented Alignment Improves Zero-Shot Respiratory Sound Classification

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel framework for zero-shot respiratory sound classification by aligning self-supervised respiratory encoders with clinical terminology. This method utilizes a medical LLM to generate structured reports from metadata, creating semantic anchors for contrastive learning. The approach combines a sigmoid-based contrastive loss with an encoder's native SSL objective and similarity-aware negative sampling to improve pathological boundary differentiation. Across multiple tasks and datasets, this framework achieved a 61.3% mean zero-shot AUC, outperforming existing models like CLAP and Qwen2-Audio, and also reached the highest linear probing AUC using significantly less data.

IMPACT This research could enhance diagnostic capabilities in healthcare by enabling more accurate and data-efficient analysis of respiratory sounds.

    Zero-Shot Respiratory Sound Classification through LLM-Augmented Audio-Text Alignment

    arXiv:2609.00055v1 Announce Type: cross Abstract: Self-supervised respiratory encoders lack semantic grounding in clinical domain needed for zero-shot inference, limiting their utility without task-specific labeled data. We propose a framework that aligns these encoders with medi…
