  The adoption of modern technologies for use in healthcare has become an
inevitable change. The emergence of artificial intelligence drives this digital
disruption. Artificial intelligence has augmented machine capabilities to act
like and interact with human beings. As the healthcare industry adopts
technology in most areas, an area in healthcare that is touched by this change
is clinical practice. New technologies are being designed to improve healthcare
services. One aspect of these technologies is voice user interfaces. This paper
reviews applications of voice user interfaces in clinical settings. Several
information sources were consulted, and based on eligibility criteria, a search
was conducted, and ten papers selected. This study presents findings from the
last ten years (2009-2019). The results are categorized based on findings, also
they contribute to the discussion and the research gaps identified for future
study as regards context-aware voice user interfaces and the appearance of
conversational agents from a given set of options.
