Audio Deep Packet Loss Concealment Challenge – INTERSPEECH 2022

Region: Global

Official rules

These Official Rules (“Rules”) govern the operation of the Microsoft M365 Core INTERSPEECH 2022 PLC (see overview) Event Contest (“Contest”). Microsoft Corporation, One Microsoft Way, Redmond, WA, 98052, USA, is the Contest sponsor (“Sponsor”).

Definitions

In these Rules, “Microsoft”, “we”, “our”, and “us”, refer to Sponsor and “you” and “yourself” refers to a Contest participant, or the parent/legal guardian of any Contest entrant who has not reached the age of majority to contractually obligate themselves in their legal place of residence. “Event” refers to the INTERSPEECH 2022 PLC (see overview) event held in Incheon, Korea (the “Event”). 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.

Entry period

The Contest will operate from January 19, 2021 to March 8, 2022 (“Entry Period”). The Entry Period is divided into several periods as described in section How to Enter.

Eligibility

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’s gift policies. Microsoft will not be party to any disputes or actions related to this matter.

PLEASE NOTE: If you are a public sector employee (government and education), all prize awards will be awarded directly to your public sector organization and subject to receipt of a gift letter signed by your agency/institution’s ethics officer, attorney, or designated executive/officer responsible for your organization’s gifts/ethics policy. Microsoft seeks to ensure that by offering items of value at no charge in promotional settings it does not create any violation of the letter or spirit of the entrant’s applicable gifts and ethics rules.

How to enter

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. Prizes will be awarded based on the speech quality of PLC models using the online subjective evaluation framework ITU-T P.808. Only models described in accepted INTERSPEECH 2022 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: January 19 2022– March 8, 2022. To register, please send an email to [email protected] stating that you are interested to participate in the challenge. Please include the following details in your email:

  • Names of the participants and name of the team captain
  • Institution/Company
  • Email

Then i. develop a speech enhancement model that best meets the Contest Objective as described more fully below and ii. submit a paper to INTERSPEECH 2022 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. On March 1, 2022, the blind test dataset will be made available. You will have until 23:59 AoE  on March 8 to test your model against this dataset and create a set of enhanced clips to submit for judging (your “Entry”).

The rules of the challenge are as follows:

  • The PLC must take less than the stride time T_s (in ms) to process a frame of size T (in ms) on an Intel Core i5 quad-core machine clocked at 2.4 GHz or equivalent processors. For example, T_s = T/2 for 50% overlap between frames. The total algorithmic latency allowed including the frame size T, stride time T_s, and any look ahead must be ≤ 20ms.
  • The PLC can be a deep model, a traditional signal processing algorithm, or a mix of the two. There are no restrictions on the PLC aside from the run time and algorithmic delay described above.
  • Submissions must follow instructions on overview page.
  • Winners will be picked based on the CCR MOS evaluated on the blind test set using ITU-T P.808 framework described in B. Naderi, R. Cutler, “An Open source Implementation of ITU-T Recommendation P.808 with Validation”, INTERSPEECH 2020
  • The blind test set will be made available to the participants on March 1, 2022. Participants must send the results (audio clips) achieved by their developed models to the organizers. We will use the submitted clips to conduct ITU-T P.808 subjective evaluation and pick the winners based on the results. Participants are forbidden from using the blind test set to retrain or tune their models. They should not submit results using other PLC methods that they are not submitting to INTERSPEECH 2022. Failing to adhere to these rules will lead to disqualification from the challenge.
  • Participants should report the computational complexity of their 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). Among the submitted proposals differing by less than 0.1 MOS, the lower complexity model will be given a higher ranking.
  • Each participating team must submit an INTERSPEECH paper that summarizes the research efforts and provide all the details to ensure reproducibility. Authors may choose to report additional objective/subjective metrics in their paper.
  • Submitted papers will undergo the standard peer-review process of INTERSPEECH 2022. The paper needs to be accepted to the conference for the participants to be eligible for the challenge.

INTERSPEECH 2022 Paper Submission and Judging Period: Until 11:59 PM anywhere-on-earth March 21, 2022 Your Entry must be described in a paper accepted by INTERSPEECH 2022. To submit a paper, visit INTERSPEECH 2022 (opens in new tab) .

  • 99% – The subjective speech quality and word error rate evaluated on the blind test set using ITU-T P.808 framework and Microsoft Azure Cognitive Services. We will use the submitted clips with no alteration to conduct these evaluations and pick the winners based on the results. Among the submitted proposals differing by less than 0.1, the lower complexity model will be given higher ranking.
  • 1% – The Entry was described in an accepted INTERSPEECH 2022 paper

Winners will be selected and notified within 7 days following the event.  In the event of a tie between any eligible entries, an additional judge will break the tie based on the judging criteria described above.
