While the popularity of voice user interfaces (VUIs) is increasing steadily, there is a lack of understanding about their impact on privacy. This has resulted in the rise of privacy concerns among users of VUI. Such privacy concerns include unwanted location tracking, unwarranted ﬁngerprinting of voice data, listening to the users’ private conversations without consent, and unwanted sharing of private data with other devices and services. In this paper, we present user research on the emotional experiences and privacy expectations of users from human-to- VUI interaction. Further, we investigate user preferences for privacy notiﬁcation modalities in a VUI, with respect to different privacy contexts. We use a sequence of qualitative and quantitative data analysis techniques to identify these aspects from our user study. To validate our ﬁndings, we implement a prototype of a privacy-aware notiﬁcation system for a VUI based application and evaluate its effectiveness. Finally, we provide guidance on improving privacy awareness of a VUI device.
