Please use Microsoft Conference Management Toolkit for submitting the results. Participants also need to register on the Challenge CMT site where they can submit the enhanced clips. To register for the challenge, participants are required to email Acoustic Echo Cancellation Challenge with the name of their team members, emails, affiliations, team name, and tentative paper title. The winners of this challenge are selected based on the average Mean Opinion Score achieved across all different single talk and double talk scenarios, and the speech recognition rate. We also open source an online subjective test framework and provide an online objective metric service for researchers to quickly test their results. These datasets consist of recordings from more than 7,500 real audio devices and human speakers in real environments, as well as a synthetic dataset. In this challenge, we open source two large datasets to train AEC models under both single talk and double talk scenarios. This is the third AEC challenge and it is enhanced by including mobile scenarios, adding speech recognition rate in the challenge goal metrics, and making the default sample rate 48 kHz. The ICASSP 2022 Acoustic Echo Cancellation Challenge 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.
