Research on Voice Search Behavior in the Last 10 Years.

ABSTRACTVoice search enables users to issue spoken information requests and retrieve desired information on web/mobile search interfaces. We conducted a literature review to examine the extent to which existing studies have addressed voice search behavior, with a focus on the employed methodologies and the focused topics in these studies. Fourteen relevant studies conducted since 2008 were identified from four publication databases. These studies were mainly focused on three aspects of search behavior: voice query characteristics, reformulation strategies, and users' perception/satisfaction. Our results provide a snapshot of how users perform and perceive voice search in order to inform future research and design of voice search systems.
