This joint workshop is a summary initiative between two projects that have been driving the research of voice biometric identification.

  • VoicePersonae aims to break down the barriers within the field of voice identity, and develop new techniques for privacy protection, security, and generative modeling of voice identities.
  • ASVspoof aims to provide benchmarking solutions to foster the development of countermeasures (CMs) to protect against the manipulation of ASV systems from spoofing attacks.

Call for Presentations

The programme kindly welcomes presentations from international speakers, covering areas of speaker recognition, speaker anonymization, speech synthesis, and spoofing detection. The workshop expects the presentation to be compact, specialized, and informative.

Please carefully read the information below for preparing the submitting your proposal of presentation.

  • Duration: Each talk will have a duration of ~20 minutes, plus a ~5-minute Q&A and a ~5-minute break between the talks.
  • Submission: Please find the link to the form below. Please find the link of form below. The title, abstract and outline of the talk can be entered in the form.

The proposals will be peer-reviewed by the technical committee. The titles of selected proposals will be posted in this page shortly after releasing the results.

Proposers of selected talks are warmly invite and encouraged to give the talk in person at Tokyo.
