SPSC Symposium

4th Symposium on Security and Privacy in Speech Communication


3rd VoicePrivacy Challenge


Submission is now open

Submit your paper here


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.

Last year's Proceedings

The proceedings are available via the ISCA Archive.

The fourth 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.

The VoicePrivacy initiative is spearheading the effort to develop privacy preservation solutions for speech technology. It aims to consolidate the newly formed community to develop the task and metrics and to benchmark progress in anonymization solutions using common datasets, protocols, and metrics. VoicePrivacy takes the form of a competitive challenge. In keeping with the previous VoicePrivacy Challenge editions, the current edition focuses on voice anonymization. Participants are required to develop anonymization systems to suppress speaker identity while keeping the content and paralinguistic attributes intact. This edition focuses on preserving the emotional state, which is the key paralinguistic attribute in many real-world applications of voice anonymization. All the participants are encouraged to submit to the SPSC Symposium papers related to their challenge entry, as well as other scientific papers related to speaker anonymization and voice privacy. More details can be found on the VoicePrivacy Challenge webpage: https://www.voiceprivacychallenge.org/.

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.

For on-side participants that also join the Interspeech 2024 please register via Interspeech, for remote or on-side participants that will only visit the SPSC Symposium please write a mail to ingo.siegert@ovgu.de

Call for Papers

The Symposium aims at laying the first building blocks required to address the question of how researchers and practitioners might bridge the gap between social perceptions and their technical counterparts with respect to what it means for our voices and speech to be secure and private. The symposium brings together researchers and practitioners across multiple disciplines – more specifically: signal processing, cryptography, security, human-computer interaction, law, and anthropology. By integrating different disciplinary perspectives on speech-enabled technology and applications, the SPSC Symposium opens opportunities to collect and merge input regarding technical and social practices, as well as a deeper understanding of the situated ethics at play.

The SPSC Symposium addresses interdisciplinary topics.

For more details, see Full CfP

SPSC Topics regarding the technical perspective and the humanities view include, but are not limited to:

  • Speech Communication on the sense of security and privacy
  • Cybersecurity for speech processing
  • Machine Learning to increase security and privacy
  • Natural Language Processing and privacy
  • Human-Computer Interfaces (Speech as Medium)
  • Ethics & Law
  • Digital Humanities


Papers intended for the SPSC Symposium should be up to eight pages of text. The length should be chosen appropriately to present the topic to an interdisciplinary community. Paper submissions must conform to the format defined in the paper preparation guidelines and as detailed in the author's kit. Papers must be submitted via the online paper submission system via the Link on the SPSC Website. The working language of the conference is English, and papers must be written in English. All accepted papers will be published in the ISCA archive alongside Interspeech papers and related ISCA workshops. The overleaf template can be found here, the author's kit for local LateX here.
