The ICASSP 2026 URGENT Challenge advances the series by focusing on universal speech enhancement (SE) systems that handle diverse distortions, domains, and input conditions. This overview paper details the challenge's motivation, task definitions, datasets, baseline systems, evaluation protocols, and results. The challenge is divided into two complementary tracks. Track 1 focuses on universal speech enhancement, while Track 2 introduces speech quality assessment for enhanced speech. The challenge attracted over 80 team registrations, with 29 submitting valid entries, demonstrating significant community interest in robust SE technologies.

翻译：ICASSP 2026 URGENT挑战赛延续了该系列的传统，重点关注能够处理多种失真、领域及输入条件的通用语音增强系统。本综述论文详细阐述了该挑战赛的设立动机、任务定义、数据集、基线系统、评估协议及结果。挑战赛分为两个互补的赛道：赛道1专注于通用语音增强，而赛道2则引入了针对增强语音的语音质量评估。本次挑战赛吸引了超过80支团队注册，其中29支团队提交了有效参赛作品，充分展现了学术界对鲁棒语音增强技术的浓厚兴趣。
