Usability of Voice Assistants in Healthcare: A Systematic Literature Review

Over the last decades, the rapid development and applications of voice assistants (VA) have been integrated into healthcare systems worldwide. With the high acceptance rate of voice assistants, usability is the key aspect that must be examined to ensure effective and accurate performance in the critical and sensitive environment of healthcare. Based on our research, not many studies reviewed the usability of voice assistants in healthcare and thus creating a notable gap in the literature regarding the usage of VA in healthcare. This study presents a qualitative systematic review of the usability of VA in healthcare with a breakdown of five major categories where VAs serve in healthcare. A total of 18 papers contained supportive evidence for the review and summarizes the roles and usages of VA in healthcare along with existing applications in healthcare systems. Based on the reviewed studies, limitations of VA and recommendations for future research to ensure effective and reliable applications of VA in healthcare are reported.
