Voice User Interfaces (VUI)  —  The Ultimate Designer’s Guide

VUI known as Voice User Interfaces. A topic even the general public is quite aware of thanks to the marketing powers of the Amazon Alexa. In the US, Google Assistant, Cortana, Siri, Alexa, have all been interacted with at some point due to the integrations we see on Mobile, Home, and Cars.

I’ve always been an early adopter of technology, but it wasn’t till I sat with my dad and watched him talk into his controller to search for a tv show that I started taking VUI seriously. ( Yes I use my father as my benchmark for UX trends I need to focus on 😆)

As technology rapidly advances its essential to understand user needs instead of forcing extra ways of interacting with the devices in our lives. Ethnographic research is more important than ever to know if the users you are going to build for will accept these new ways of interaction. I believe VUI genuinely will become one of if not the core way we interact with devices in the future but understanding exactly were to apply it and if it makes our lives better is the most critical question to be answered.


An effective voice motion experience would benefit from the following principles:

  • Transitory — Seamlessly handles transitions between different states. The user should feel like they are never waiting, but rather that the assistant is working for them.

  • Vivid— Vivid color conveys delight and futurism. It adds an element of futuristic elegance to the interaction — which encourages repeat interaction.

  • Responsive — Responds to user input and gesturing. Gives hints regarding which words are being processed and allows the user to see if their speech/intent is being accurately parsed.
