Understanding Privacy in Smart Speakers: A Narrative Review

With the rise in the widespread use of smart speakers, voice-based interactions have become increasingly convenient with their accessibility benefits. However, the inherent "always on" feature of these devices has amplified user privacy concerns, especially given their pervasive presence in homes. To examine this complex phenomenon, we performed a narrative review to understand diverse perspectives on various perspectives on privacy related to smart speakers. Our analysis highlights the intricate landscape of privacy, encompassing its implementation, perception, and action. Notably, current literature often fails to address these dimensions of privacy in a comprehensive manner. Consequently, future research should adopt a holistic perspective on privacy in this rapidly evolving domain.
