YouTube videos are a great source Multi-speaker environments Varying audio quality andbackground channel noise Freely availableStudio InterviewsRed Carpet InterviewsOutdoor and pitch InterviewsVoxSRC

Fully Automated PipelineVoxSRCAim: Automatically obtain audio segments of speakers from videos uploadedto YouTubeTo do this we need to solve the following: When is a person speaking? Done using Active Speaker Verification (ASV)Which speaker is the celebrity that we want? Done using Face Verification

The VoxCeleb Speaker RecognitionChallenge

VoxSRC 2019VoxSRC The goal of this challenge is to probe how well currentmethods can recognize speakers from speech obtained'in the wild’. A new dataset has been collected for evaluation. VoxCeleb1 test sets are used for validation.

VoxSRC 2019 test setVoxSRC 500 speakers, 19K utterances, 208K pairs Collected using a similar pipeline to VoxCeleb From YouTube videos of celebrities that do not appearin the VoxCeleb datasets 90% of the impostor pairs are from same gender All utterances are at least 4 seconds in length

VoxSRC 2019 test set Manual verification of allspeech segments In addition, annotators payparticular attention toexamples whose speakerembeddings are far fromcluster centresVoxSRC

VoxSRC 2019 - TracksVoxSRC Fixed: Participants can train only on the VoxCeleb2dev dataset for which we have already releasedspeaker verification labels. Open: Participants can use the VoxCeleb datasetsand any other data (including that which is not publiclyreleased) except the challenge's test data.
