Interspeech 2021 Deep Noise Suppression Challenge
This challenge provides a benchmark and dataset for researchers in speech processing to develop real-time noise suppression algorithms, addressing the problem of poor speech quality in noisy environments for users of communication systems.
This paper describes the Interspeech 2021 Deep Noise Suppression (DNS) Challenge, which aims to advance noise suppression technology for improved perceptual speech quality. The challenge expands on previous iterations by including full-band scenarios and providing a new non-intrusive objective speech quality metric called DNSMOS.
The Deep Noise Suppression (DNS) challenge is designed to foster innovation in the area of noise suppression to achieve superior perceptual speech quality. We recently organized a DNS challenge special session at INTERSPEECH and ICASSP 2020. We open-sourced training and test datasets for the wideband scenario. We also open-sourced a subjective evaluation framework based on ITU-T standard P.808, which was also used to evaluate participants of the challenge. Many researchers from academia and industry made significant contributions to push the field forward, yet even the best noise suppressor was far from achieving superior speech quality in challenging scenarios. In this version of the challenge organized at INTERSPEECH 2021, we are expanding both our training and test datasets to accommodate full band scenarios. The two tracks in this challenge will focus on real-time denoising for (i) wide band, and(ii) full band scenarios. We are also making available a reliable non-intrusive objective speech quality metric called DNSMOS for the participants to use during their development phase.
