Voice User Interface
Voice User Interfaces (VUI) allow us to interact with a system via voice controls. Some famous examples of VUI are Siri, Google Assistant and Alexa. What is the real advantage of a VUI? It allows users to interact directly with an assistant while taking care of other activities.
Designing a VUI is critical because this system lacks a graphic interface. The user must clearly understand the machine’s possible interactions and functionalities. For a VUI to be successful, it must have an excellent understanding of spoken language and be able to instruct the user to specific vocal commands and the type of operating interactions. Furthermore, the complexity of dialogue via VUI obliges the designer to create a simple structure for the user, as much ‘human’ as possible.
