Smart speakers and virtual assistants are part of our daily life. Their applications find not only use in our homes, where speech technology grants an unprecedented level of convenience, but also in health care, forensic sciences as well as in banking and payment methods; speech technology has dual use applications. By consequence, we need to evolve our understanding of security & privacy for applications in speech communication.
SPSC features two formats.
- Webinar — Once-a-month web seminars. The lectures range from keynote-style talks of seniors in industry and academia to practice talks of doctoral and master defenses. We try to keep the time slot for the first Monday in a month (not a bank day) at 10h CET. But we are flexible with the scheduling (for both day and time).
Duration. 40 minutes talk & up to 20 minutes Q&A. - Café Journal Club — We meet for a Café session and discuss current topics and papers related to the work we are doing. Bring a tea, coffee or your favorite beverage. Let's exchange knowledge and ideas. Young researchers decide the topic for an interactive debate and ideas for collaboration. This is an excellent opportunity to meet other researchers in the field, expand your professional network, and find potential collaborators on a project. In the first part of the meeting we will be discussing a paper or topic (30 minutes), followed by 10 minutes of discussing ideas. We will meet once per month, similar to the Webinar, but near the end of the month. Meeting duration 30 minutes with 10 minutes of discussion. We are happy to receive suggestions on interesting papers and topics, and also open to participants as volunteer meeting leader.
Duration. 30 minutes followed by 10 minutes discussion.
Outcome. The goal of the lecture talks is to understand another perspective and discuss on particular aspects of SPSC in its inter-disciplinary setting. We need to leave our comfort zones to meaningfully anticipate the merger of speech technology with SPSC research areas including: user-interface design, study of the law, cryptography, and cognitive sciences.
Open to everyone. Including non-members (0 EUR fee). Please register for stating your data privacy consent and to obtain the session URL.

Privacy in Health Oriented Paralinguistic and Extralinguistic Tasks
Abstract [+]
In this talk we provide a brief overview of the current state-of-the-art in paralinguistic and extralinguistic tasks for a major application area in terms of privacy concerns - health, along with an introduction to cryptographic methods commonly used in privacy-preserving machine learning. These will lay the groundwork for the review of the state-of-the-art of privacy in paralinguistic and extralinguistic tasks for health applications. With this talk we hope to raise awareness to the problem of preserving privacy in this type of tasks and provide an initial background for those who aim to contribute to this topic.
