Design and Evaluation of Voice User Interfaces: What Should One Consider?

Voice user interfaces (VUI) come in various forms of software or hardware, are controlled by voice, and can help the user in their daily life. Despite VUIs being readily available on smartphones, they have a low adoption rate. This can be attributed to challenges such as the misunderstanding of voice commands as well as privacy and data security concerns. Still, there are intensive VUI users, but they also raise concerns that may be independent of culture. Hence, we will discuss in our paper the various areas that should be considered when developing VUIs to increase user acceptance and foster a positive user experience (UX). We propose exploring the context of use and UX aspects to understand users’ needs while using VUIs. All of our suggestions can help VUI developers to design better VUIs.
