ICASSP 2021 Acoustic Echo Cancellation Challenge
The ICASSP 2021 Acoustic Echo Cancellation Challenge (opens in new tab) is intended to stimulate research in the area of acoustic echo cancellation (AEC), which is an important part of speech enhancement and still a top issue in audio communication and conferencing systems. We received 17 submissions for the challenge from industry and academic universities. Microsoft is happy to announce the winners of the ICASSP 2021 Acoustic Echo Cancellation Challenge.
