SPSC Symposium and VPC Challenge
6th Symposium on Security and Privacy in Speech Communication joined with 4th VPC Challenge
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 VPC Challenge Organizers.

The 6th edition of the Symposium on Security & Privacy in Speech Communication focuses on speech and voice as central media through which humans convey intentions, emotions, and identity in both everyday and professional contexts. Spoken interaction now underpins virtual assistants, biometric services, and sensitive applications in sectors such as healthcare, forensics, and commerce. The symposium invites contributions that address how we can strengthen security and privacy for diverse speech representation types in user-centric human–machine interaction, while preserving usability and trust. To this end, it fosters interdisciplinary exchange and aims to bring together researchers and practitioners from multiple fields, including signal processing, cryptography, security, human–computer interaction, law, ethics, and anthropology. This symposium continues the successful series of events stemming from the ISCA special interest group on Security & Privacy in Speech Communication (SPSC-SIG), where perspectives from technological and humanities communities mutually inform and enrich one another to develop multidisciplinary and interdisciplinary skills.
For the general symposium, we welcome contributions on related topics, as well as progress reports, project dissemination, 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 submitting their own contribution. Building on community efforts such as the VoicePrivacy Challenge and related benchmarks, the symposium explicitly welcomes VoicePrivacy 2026 Challenge participants to submit papers related to their challenge contributions and broader work on voice privacy and speaker anonymization. While we aim to meet all participants on-site, virtual presentations will also be possible during the symposium. More details regarding the challenge can be found at VPC Challenge Webside.
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
Submission:
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 or use the Overleaf Template.
Submission system is open:
Reviews:
At least three double-blind reviews are provided, and we aim to obtain feedback from interdisciplinary experts for each submission.
