So, as an inspired designer, if you’re as excited as I am and want to give a chance to the voice-based AI, then you need to fine-tune your skills and knowledge on how to design voice user interfaces. Fortunately, you stumbled at the right article. Here is everything you’d like and need to know about VUI.

Voice user interface or VUI is the interface that allows users to use voice commands to interact with a system. Google Assistant, Siri, and Amazon’s Alexa are among the most popular and top voice user interface examples.

VUIs have the greatest benefit of promoting an eye-free and hands-free way of communicating with a program. Similar to mobile apps running on any OS and system, VUI has three layers that need to work together to effectively communicate with the voice. Each of the three layers here uses the layer below it, thus promoting the layer above. This is the upper two layers where the voice interface resides in the cloud, not on the computer.

Reasons Why Voice Is Becoming Famous

• Speaking is more natural than typing
• Helps technology be prevalent
• Moore’s law
• More practical for specially-abled

Difference between Voice and Other Forms of UI

Since we have different types of user interfaces available, understanding the different points between them will enable the VUI to be viewed in greater depth.

• Speed
• Text vs. natural language vs. gestures
• Privacy

Steps for Designing the Voice User Interface

• Research your audience
• Define
• Create a prototype
• Test your product
• Refine

Design Guidelines for Voice User Interface

• Keep it simple and short
• Let users know they are being heard
• Confirm when the task is done

Challenges of Designing VUI
