Welcome to the 2022 VoxCeleb Speaker Recognition Challenge! The goal of this challenge is to probe how well current methods can recognize speakers from speech obtained 'in the wild'. The data is obtained from YouTube videos of celebrity interviews, as well as news shows, talk shows, and debates - consisting of audio from both professionally edited videos as well as more casual conversational audio in which background noise, laughter, and other artefacts are observed in a range of recording environments.
The workshop will be held in junction with Interspeech 2022.
Workshop page is now open. Please visit here for more information.
The workshop deadline has been extended until 14th September 2022, 23:59:59 UTC.

VoxSRC-22 will feature four tracks, including a brand new semi-supervised domain adaptation track. Track 1, 2 and 3 are speaker verification tracks, where the task is to determine whether two samples of speech are from the same person. Track 4 is a speaker diarisation track, where the task is to break up multi-speaker audio into homogenous single speaker segments, effectively solving ‘who spoke when’.

This year, for the fully supervised tracks (1 & 2) we focus on two challenging settings. First, we focus on how speech segments taken from the same speaker at different ages impact speaker verification systems. Secondly, we focus on how speaker verification systems perform when speech segments from different speakers have the same background noise.
This year, we introduce a new track (track 3), focused on semi-supervised domain adaptation. Here, we are interested in the problem of how models, pre-trained on a large set of data with labels in a source domain, can adapt to a new target domain given: (1) a large set of unlabeled data from the target domain, and (2) a small set of labeled data from the target domain.
In this track, we are interested in the domain adaptation task in speaker verification from one language in a source domain, to a different language in a target domain. Specifically, the source domain consists of mainly English-speaking utterances, and the target domain consists of Chinese-speaking utterances. Here, we use the VoxCeleb2 data as the source domain, and Cn-Celeb data as the target domain. Note that we only use a specific subset of Cn-Celeb, as defined in the following Section.
VoxCeleb2 data consists of mainly interview-style utterances, whereas Cn-Celeb consists of several different genres of utterances. In order to focus on the language domain adaptation task, we have therefore removed utterances in the target domain from the “singing”, “play”, “movie”, “advertisement”, and “drama” genres. We thank the authors of CN-Celeb for allowing the use of their dataset for the target domain in this track.
This year, we follow the same protocol for tracks 1 & 2 as in previous years, and we introduce a new protocol and set of data requirements for track 3.
Note : We've recently found some duplicates in Track 1 & 2 validation trial pairs. (1236 pairs) The fixed version of new trial pairs are uploaded as "Track 1 & 2 validation trial pairs(fixed)" so please download them.

For the Speaker Verification tracks, we will display both the Equal Error Rate (EER) and the Minimum Detection Cost (CDet). For tracks 1 and 2, the primary metric for the challenge will be the Detection Cost, and the final ranking of the leaderboard will be determined using this score alone. For track 3, the primary metric is EER, as this is a more forgiving metric.
For the Speaker Diarisation track, we will display both the Diarisation Error Rate (DER) and the Jaccard Error Rate (JER), but the leaderboard will be ranked using the Diarisation Error Rate (DER) only.
We use a collar of 0.25 seconds and include overlapping speech in the scoring. For more details, consult section 6.1 of the NIST RT-09 evaluation plan.
Four tracks will be held via Codalab platform. You need a Codalab account for registration, so please make it if you don't have one. Any researchers, whether in academia or industry, can participate in our challenge, but we only accept institutional emails to register. Please follow the instructions on each challenge website for submission.CodaLab evaluation server are active now. Please visit the links below for participation.
Q. Who is allowed to participate? A. Any researcher, whether in academia or industry, is invited to participate in VoxSRC . We only request a valid official email address, associated with an institution for registration, once the registration system opens. This ensures we limit the number of submissions per team. Q: Do I need to use the name of my institution or my real name as the team name for a submission? A: No, you do not have to. The name of the CodaLab user (or the Team name, if you have set up one in CodaLab) that uploads the submission will be used in the public leaderboard. Hence if you do not want your details to be public, you should anonymise if appropriate. You must select a team name before the server's closing time. Q: For the semi-supervised track 3, can I train on all of CnCeleb? A: No. For track 3, participants may only train on (1) a subset of CnCeleb without labels (we provide the subset under the name “Track_3_unsupervised_target_domain_data.txt” in the “data” section), and (2) a small set of CnCeleb with labels (we provide this set under the name “Track 3 supervised target domain data” in the “data” section) Q: For the semi-supervised track 3, can I use my model that I trained for the closed track 1? A: Yes. For track 3, participants are allowed to train on the VoxCeleb2 dev dataset. So participants can use their model that was trained for track 1. Q: For the semi-supervised track 3, can I use the CnCeleb validation set? A: No. For track 3, participants can only use the provided validation set. Q. Can I participate in only some tracks? A. Yes, you can participate in as many tracks as you like and be considered for each one independantly. Q: How many submissions can I make? A: You can only make 1 submission per day. In total, you can make only 10 submissions to the test set for each track. Q: Can I train on other external datasets (public, or not)? A: Only for the OPEN tracks. Not for the CLOSED tracks. Q: Can I use data augmentation? A: Yes, you can use any kind of noise or music, as long as you are not training on additional speech data, for the CLOSED tracks. You may also use the MUSAN noise dataset as augmentation for the CLOSED tracks. For the OPEN track, you can train on any data you see fit. Q. Can I participate in the challenge but not submit a report describing my method? A. We do not allow that option. Entries to the challenge will only be considered if a technical report is submitted on time. This should not affect later publications of your method if you restrict your report to 2 pages including references. You can still submit to the leaderboard, however, even if you do not submit a technical report. Q. Will the technical report submitted to this workshop be archived by Interspeech 2022? A. No. We shall use the papers to select some authors to present their work at the workshop. Q. Will there be prizes for the winners? A. Yes, there will be cash prizes for the top 3 on the leaderboard for each track. Q. For the CLOSED condition, can I use the validation set for training anything, eg. the PLDA parameters? A. No, for the CLOSED condition you can use the validation set only to tune user-defined hyperparameters, eg. for example selecting which convolutional model to use. Q. For the CLOSED conditions, what can I use as the validation set? A. For the closed conditions, participants may only use the provided pairs for this year's challenge, or the VoxCeleb1 pairs. These must strictly NOT be used for training. It is beneficial for participants to use this year's provided validation pairs, as their distribution matches that of the hidden test pairs. Q. What kind of supervision can I use when training without labels in the semi-supervised track? A. Self-supervision is an increasingly popular field of machine learning which does not use manually labelled training data for a particular task. The supervision for training instead comes from the data itself, for example from the future frames of a video or from another modality, such as faces. Q. For the semi-supervised track, when I am training on the large set of target domain data without labels, can I use the total number of speakers in the CnCeleb2 dev set as a hyperparameter? A. No, you cannot use any speaker identity information at all. You cannot use the number of speakers in any way, e.g. to determine the number of clusters for a clustering algorithm. Q. What if I have an additional question about the competition? A. If you are registered in the CodaLab competition, please post your question in the competition forum (rather than contact the organizers directly by e-mail) and we will answer it as soon as possible. The reason for this approach is that others may have similar questions: use of the forum ensures that the question can be useful for everyone. If you rather make your question before registering, please follow the procedure in the Organisers section below.
