A voice user interface (VUI) allows people to use voice commands to control computers and various devices. The VUIs are rapidly evolving; the item is destined to be the next major upheaval in the IT sector. In recent years, the experiences of voice interaction have reached the general public through the diffusion of virtual assistants such as Google Home and Amazon Alexa.
Voice interaction is a new way of connecting with customers; voice experiences work well when they offer a faster, easier, or more enjoyable way of doing things. Voice user interfaces do not solve new problems…. yet. But they solve existing problems in new ways that significantly improve the lives of many people.
