Many recent AEC studies report reasonable performance on synthetic datasets where the train and test samples come from the same underlying distribution. However, the AEC performance often degrades significantly on real recordings. Also, most of the conventional objective metrics such as\u00a0echo return loss enhancement<\/i>\u00a0(ERLE) and\u00a0perceptual evaluation of speech quality<\/i>\u00a0(PESQ) do not correlate well with subjective speech quality tests in the presence of background noise and reverberation found in realistic environments.<\/p>\n 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 2,500 real audio devices and human speakers in real environments, as well as a synthetic dataset. We open source an online subjective test framework based on ITU-T P.808 for researchers to quickly test their results. The winners of this challenge will be selected based on the average P.808 Mean Opinion Score (MOS) achieved across all different single talk and double talk scenarios.<\/p>\n Please use\u00a0Microsoft Conference Management Toolkit<\/a>\u00a0for submitting the results. After logging in, complete the following steps to submit the results:<\/p>\n Submission deadline<\/b>: Oct 9, 2020, 11:59pm (anywhere on Earth)<\/p>\n For questions, please contact\u00a0aec_challenge@microsoft.com<\/a><\/p>\n\n\n\n\n\n SPONSOR<\/p>\n These Official Rules (“Rules”) govern the operation of the Microsoft M365 Core ICASSP 2021 AEC (see overview) Event Contest (“Contest”).

Prizes will be awarded based on the speech quality of AEC models using the online subjective evaluation framework ITU-T P.808. Only models described in accepted ICASSP 2021 papers will be eligible for prizes. See (yet to upload the paper) for additional Contest details. You may participate as an individual or a team. If forming a team, you must designate a “Team Captain” who will submit all entry materials on behalf of the team and act as the recipient of any prizes that the team may win. 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: September 7 – October 19, 2020. To register, please send an email to aec_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 (yet to be uploaded) and ii. submit a paper to ICASSP 2021 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.<\/p>\n The final evaluation will be conducted on a blind test set that is similar to the open sourced test set. Testing \/ Entry Period: September 8 – October 16, 2020. On October 2, the blind test dataset will be made available. You will have until 11:59 PM PT on October 9 to test your model against this dataset and create a set of enhanced clips to submit for judging (your “Entry”).<\/p>\n The rules of the challenge are as follows:<\/p>\n ICASSP 2021 Paper Submission and Judging Period: October 19, 2020 – 11:59 PM PT January 22, 2021 Your Entry must be described in a paper accepted by ICASSP 2021.
