Description

Speaker verification (SV) is the task of verifying whether an input utterance matches the claimed identity. The success of speaker verification systems heavily depends on large training datasets collected under real-world conditions. While common languages like English or Chinese have vastly available datasets, low-resource ones like Vietnamese remain limited. With the aim to leverage the development of Vietnamese speaker verification, the Vietnamese Spoofing-Aware Speaker Verification Challenge (VSASV) 2023 has been designed for understanding and comparing research SV techniques on Vietnam-Celeb, a large-scale dataset for Vietnamese speaker recognition.

This is the first spoofing-aware speaker verification challenge for Vietnamese. While the evaluation metric is the same as speaker verification - Equal Error Rate - we introduce spoofed negative samples created by synthesizing speech from target speakers or recording speech from different devices. By doing this, we encourage participants to develop SV systems that are jointly optimized for spoofing detection and speaker verification.

Basic Regulations:

Any use of external speaker data and pre-trained models is PROHIBITED, even for pre-trained models on other tasks, e.g. speech recognition, text-to-speech, speech enhancement, voice activity detection...

Participants can use non-speech data (noise samples, impulse responses…) for augmenting and must specify and share with other teams.

Participants can create spoofed samples only with the provided data.

Participants can use data augmentation techniques only with the provided data from the organizer.

The challenge has a public and a private test set. The final standings for the task will be decided based on private test results. Teams may be required to provide source code to examine the final results.

Evaluation data

This task has a public and private test sets. Final standings for the task will be decided based on private test results.

Detailed information about each set:

  • Public test: the public test contains both bona fide (real speech) and spoofed negative samples. The negative pairs are chosen randomly.

  • Private test: the private test set contains both bona fide and spoofed negative samples. The bona fide negative pairs are chosen such that the speakers have the same gender and dialect.

Evaluation metric

The performance of the models will be evaluated by the Equal Error Rate (EER) where the False Acceptance Rate (FAR) equals the False Rejection Rate (FRR).

Submission Guidelines

Multiple submissions are allowed but under a limitation of each phase, the evaluation result is based on the submission having the lowest EER.

The submission file comprises a header, a set of testing pairs, and a cosine similarity output by the system for the pair. The order of the pairs in the submission file must follow the same order as the pair list. A single line must contain 3 fields separated by tab character in the following format:

test_wav<TAB>enrollment_wav <TAB>score<NEWLINE>

where

enrollment_wav - The enrollment utterance
test_wav - The test utterance
score - The similarity score

  • Prizes are subject to the Competition Organizer’s review and verification of the entrant’s eligibility and compliance with these rules as well as the compliance of the winning submissions with the submission requirements.

  • Participants grant to the Competition Organizer the right to use your winning submissions and the source code and data created for and used to generate the submission for any purpose whatsoever and without further approval.

Eligibility

  • Each participant must create a AIHub account to submit their solution for the competition. Only one account per user is allowed.

  • The competition is public, but the Competition Organizer may elect to disallow participation according to its own considerations.

  • The Competition Organizer reserves the right to disqualify any entrant from the competition if, in the Competition Organizer’s sole discretion, it reasonably believes that the entrant has attempted to undermine the legitimate operation of the competition through cheating, deception, or other unfair playing practices.

Team

  • Participants are allowed to form teams. 

  • You may not participate in more than one team. Each team member must be a single individual operating a separate AIHub account. 

Submission

    • Public Test: 20 submissions / day / team
    • Private Test: 6 submissions in total
  • Submissions are void if they are in whole or part illegible, incomplete, damaged, altered, counterfeit, obtained through fraudulent means, or late. The Competition Organizer reserves the right, in its sole discretion, to disqualify any entrant who makes a submission that does not adhere to all requirements.
