Exploring Text-Queried Sound Event Detection with Audio Source Separation

ICASSP 2025accepted

In sound event detection (SED), overlapping sound events pose a significant challenge, as certain events can be easily masked by background noise or other events, resulting in poor detection performance. To address this issue, we propose the text-queried SED (TQ-SED) framework. Specifically, we firs…
