ISCA SPSC Symposium

3rd Symposium on Security and Privacy in Speech Communication

August 19, 2023 co-located with Interspeech 2023

Dublin City University (Dublin, Ireland)

Submission link


Speech and voice are media through which we express ourselves. Speech communication can be used to command virtual assistants, to transport emotion or to identify oneself. How can we strengthen security and privacy for speech representation types in user-centric human/machine interaction?

Interdisciplinary exchange is in high demand. The need to better understand and develop user-centric security solutions and privacy safeguard in speech communication is of growing importance for commercial, forensic, and government applications. The SPSC Symposium is a platform to seek better designed services and products as well as better informed policy papers for legislators and governance. The symposium is organized by the ISCA SPSC special interest group and the VoicePrivacy Challenge Team.


The proceedings are available via the ISCA Archive.

The third edition of the Symposium on Security & Privacy in Speech Communication, focuses on speech and voice through which we express ourselves. As speech communication can be used to command virtual assistants to transport emotion or to identify oneself, the symposium encourages participants to give answers on how we can strengthen security and privacy for speech representation types in user-centric human/machine interaction? The symposium therefore sees that interdisciplinary exchange is in high demand and aims to bring together researchers and practitioners across multiple disciplines – more specifically: signal processing, cryptography, security, human-computer interaction, law, ethics, and anthropology.

For the general symposium, we welcome contributions to related topics, as well as progress reports, project dissemination, or theoretical discussions and “work in progress”. In addition, guests from academia, industry and public institutions as well as interested students are welcome to attend the conference without having to make their own contribution.

Although, we aim for meeting all of you on-site, we also opt for virtual presentations during the symposium.


Registration fees for the event:

  • In person (Dublin City University, Dublin Ireland) Full: 38€
  • In person (Dublin City University, Dublin Ireland) Student: 24€
