The increased use of voice user interfaces has raised concerns about users’ privacy. Previous research has shown that users’ subjective experiences of privacy do not always correspond to the objective level of privacy provided by a system. This thesis examines users’ subjective experiences of privacy in voice user interfaces. The aim of the study is to investigate how interface features, interaction, and the usage of environment and context shape the experience of privacy. The study is conducted as a literature review. As a theoretical framework, the thesis draws on Sandra Petronio’s Communication Privacy Management (CPM) theory and Helen Nissenbaum’s theory of Contextual Integrity. In addition, the experience of privacy is examined from the perspective of privacy-supporting design principles. The results indicate that users’ sense of control and the transparency of system operation play a central role in shaping the experience of privacy. By strengthening users’ sense of control and the predictability of system behavior, it is possible to reduce fears of surveillance and the resulting behavioral constraints. The experience of privacy is particularly weakened in situations where data flows, data-sharing practices, and data recipients are unclear. Voice user interfaces should therefore support the experience of privacy through active, dialog-based communication that helps users understand system operations and maintain a sense of control.
