The\u202fICASSP 2022<\/a>\u202fAcoustic Echo Cancellation Challenge is intended to stimulate research in the area of\u202facoustic echo cancellation\u202f(AEC), which is an important part of speech enhancement and still a top issue in audio communication and conferencing systems. 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. In this challenge, we open source two large datasets to train AEC models under both single talk and double talk scenarios. 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. We also open source an online subjective test framework and provide an online objective metric service for researchers to quickly test their results. 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.<\/p>\n To register for the challenge,\u202fparticipants are required to email Acoustic Echo Cancellation Challenge aec_challenge@microsoft.com<\/a> with the name of their team members, emails, affiliations, team name, and tentative paper title. Participants also need to register on the Challenge CMT<\/a> site where they can submit the enhanced clips.<\/p>\n Please use\u00a0Microsoft Conference Management Toolkit<\/a>\u00a0for submitting the results.

By entering you (your parent\/legal guardian if you are not the age of majority in your legal place of residence) agree to be bound by these Rules.<\/p>\n The Contest will operate from December 1, 2021 to February 3, 2022 (\u201cEntry Period\u201d). The Entry Period is divided into several periods as described in section How to Enter.<\/p>\n Open to any registered Event attendee 18 years of age or older. If you are 18 years of age or older but have not reached the age of majority in your legal place of residence, then you must have consent of a parent\/legal guardian. Employees and directors of Microsoft Corporation and its subsidiaries, affiliates, advertising agencies, and Contest Parties are not eligible, nor are persons involved in the execution or administration of this promotion, or the family members of each above (parents, children, siblings, spouse\/domestic partners, or individuals residing in the same household). Void in Cuba, Iran, North Korea, Sudan, Syria, Region of Crimea, and where prohibited. For business\/tradeshow events: If you are attending the Event in your capacity as an employee, it is your sole responsibility to comply with your employer\u2019s gift policies. Microsoft will not be party to any disputes or actions related to this matter.<\/p>\n The Contest Objective is to promote collaborative research in real-time single-channel Speech Enhancement aimed to maximize the subjective (perceptual) quality of the enhanced speech. Winners will be determined based on the speech quality of AEC models using the online subjective evaluation framework ITU-T P.831. Only models described in accepted ICASSP 2022 Grand Challenge papers will be eligible for winning the Contest. See ICASSP 2022 Acoustic Echo Cancellation Challenge<\/a> for additional Contest details. You may participate as an individual or a team. If forming a team, you must designate a \u201cTeam Captain\u201d who will submit all entry materials on behalf of the team. Once you register as part of a Team, you cannot change Teams or alter your current team (either by adding or removing members) after the submission of your Entry. Limit one Entry per person and per team. You may not compete on multiple teams and you may not enter individually and on a team. We are not responsible for Entries that we do not receive for any reason, or for Entries that we receive but are not decipherable or not functional for any reason. Each Team is solely responsible for its own cooperation and teamwork. In no event will Microsoft officiate in any dispute regarding the conduct or cooperation of any Team or its members. The Contest will operate as follows: Registration \/ Development Period: December 1, 2021 to January 15, 2022. To register, please send an email to\u00a0aec_challenge@microsoft.com<\/a> stating that you are interested to participate in the challenge. Please include the following details in your email:<\/p>\n Then, i. develop a speech enhancement model that best meets the Contest Objective as described more fully at ICASSP 2022 Acoustic Echo Cancellation Challenge<\/a> and ii. submit a ICASSP 2022 Grand Challenge paper via Microsoft Conference Management Toolkit<\/a>\u00a0 which reports the computational complexity of the model in terms of the number of parameters and the time it takes to infer a frame on a particular CPU (preferably Intel Core i5 quad core machine clocked at 2.4 GHz). To develop your model, use any publicly available dataset for training data, including the Contest datasets provided for training and developing models. You may augment your datasets with the Contest dataset. You can augment your data in any way that improves the performance of your model. The final evaluation will be conducted on a blind test set that is similar to the open sourced test set. Testing \/ Entry Period: January 15 \u2013 January 20, 2022. On January 15, the blind test dataset will be made available. You will have until 11:59 PM PT on January 20 to test your model against this dataset and create a set of enhanced clips to submit for judging (your \u201cEntry\u201d).
