The document outlines the concept of Voice User Interface (VUI) design, highlighting its role in allowing users to interact with devices through voice commands, addressing issues like screen fatigue. It discusses the technological foundations of VUI—including AI advancements—and mentions applications in various devices, emphasizing the growing adoption of voice-controlled technologies. Stellar Digital, established in 2015, aims to provide digital solutions and expresses a commitment to client satisfaction and innovation in VUI design.

3. The voice user interface, often known as the VUI, has broken the silence between
machines and humans.
Are you curious about the popularity of voice-activated devices or virtual
assistants?
We'll have to dig a little deeper to get the answers to these questions. The massive
proliferation of smart speakers and VUI is even more clear in a recent Google post
titled
"How voice help is influencing customer behaviour." According to a Google report,
41% of people who own a voice-controlled speaker wish to converse with someone
else.
Does this make you wonder if VUI has changed the human-device relationship?
The answer is that it completely relies on you, but before we jump to a conclusion,
let's review what a voice user interface is and how it functions?

4. Voice user interface (VUI) allows a user to communicate with a device or app
using voice commands. With the increased usage of digital devices, screen fatigue
has become a more widespread issue.
As a result, the creation and deployment of speech user interfaces has become
even more advantageous. Without having to glance at the screen, VUI provides
hands-free, comprehensive control over devices and apps.
Voice-enabled AI assistants and voice-controlled products were established or
developed by the world's biggest companies, particularly the big five tech firms like
Microsoft, Google, Amazon, Apple, and Facebook.

5. The voice UI is the product of a combination of AI technologies such as automatic speech
recognition, speech synthesis, and name entity recognition. Voice user interfaces can be added
to devices or embedded into applications.
Where the VUIs process the user's voice and speech, the backend infrastructure and the VUI's
speech components backed by AI technologies are usually stored on a public or private cloud.
The device receives a response from AI technology, which recognises the user's purpose.
Different types of VUI devices:
• IoT (lights, thermostats, locks)
• Smart speakers
• Smartphones
• Desktop computer laptops
• Wearables like smartwatches
• Sound systems, smart TVs

6. User interfaces, or UIs, are the interfaces that allow machines and humans to
interact.
In recent years, one sort of UI, the visual user interface, has exploded in popularity,
surpassing typing.
Instead of typing, 71 percent of users prefer to utilise voice search for queries. Not
only that, but the number of people using voice-controlled smart speakers is
steadily rising. In the United States, more than half of smart speaker users use their
devices on a regular basis.
UX and UI designers are particularly interested in the growing popularity of voice
interfaces. After all, the ultimate goal of both is to meet the needs of consumers and
make their experience as smooth as possible.

7. The following are important considerations when building good VUI dialogue
flows:
• Maintain a conversational tone throughout the interaction.
• Create a solid mistake strategy.
• Confirm when a task is completed and add an extra layer of protection.
Some of the Apps for prototyping VUIs are in the following:
• Voiceflow- Voiceflow is a design, prototyping, and creation tool for Google
Assistant and Amazon Alexa.
• Dialogflow- Platform owned by Google for building conversational user interfaces
into webapps, mobile apps, bots, and devices.
• Speechly- Understanding spoken language is a solution to
To assist designers in creating new Alexa skills, Amazon provides its own Alexa skill
builder.

8. Voice user interface design is a fantastic concept that will grow in popularity over the
next few years. When it comes to the potential of this subject and all that it may actually
become, there is still so much for us to learn. VUIs are taking shape and evolving into
new things in the same way that UX design is.
