March 29, 2024The world of UX design is on a fast track! New tech and smart devices emerge constantly, transforming how we interact with physical and digital products. Touchscreen interfaces let us manipulate products directly, while virtual/augmented reality and voice commands offer even more ways to engage. And come to think of it, the new, highly demanded Apple Vision Pro includes these stunning features. Vision Pro features an infinite canvas that allows apps to extend beyond the limits of a standard screen. It also introduces a 3D UI that users can navigate using their voice, hands, and eyes.
Voice interaction, powered by Google Assistant, Alexa, and similar tools, enriches user experience. Designing voice UIs (VUIs) is a hot topic in the UX/UI world. Interface experts are paying close attention to how voice interactions can be enhanced. The unique nature of voice commands demands the in-depth study of VUIs, focusing on elements that significantly impact user experience.
In this short and informative read, you will learn all the hype about voice user interface and why it is the future of web browsing.
To understand voice user interface, we will first look at the basic definition, then move on to its benefits, and so on. The voice user interface is an evolving journey. This type of interface was recognized decades ago. If you have ever watched Dexter’s Laboratory (a cartoon series released in 1995), you would have noticed that it made extensive use of highly advanced voice user interface design and technology. There was a computer that would assist him and recognize his voice. Dexter could track down his sister, and overall, there was major, highly complex technology involved.
This example was given just to illustrate that voice user interfaces have always existed, and designers have always aimed to improve and advance the technology behind them.
Now, you may wonder why we gave a cartoon example. It is because this is actually all happening in reality, too! These were just simple ideas waiting to be implemented in the future.
The voice user interface is ever-evolving; we predict it will not stop. We can already see that there are flying cars, giant goggles that show us everything, AI that can help us predict certain futuristic trends, create new human-like faces and appearances, and so on. We wouldn’t be surprised if they end up creating a body suit that allows you to teleport anywhere in the world (creepy, though, but we should brace ourselves).
The design of Voice User Interface (VUI) is an ever-evolving concept. Designers need to comprehend what VUI means and how to craft effective voice interactions. Using voice commands is not just about incorporating a new feature or dialogue flow into the user journey.
While designing VUI, UI/UX professionals need to ensure a seamless user journey and that the introduction of voice commands positively impacts the user experience.
In essence, VUI is a technology that works through speech recognition principles. Users can interact with gadgets by talking to them, just like human communication.
This makes voice interaction unique, attractive, and challenging at the same time. Designers must incorporate a casual user interface within the existing graphical user interface to make the experience better and familiar for the target audience.
Just as the name suggests, the voice user interface design uses intelligence based on voice commands and recognition. This ensures a seamless user experience. Voice commands are said to be more efficient and easy to interact with as they require a blend of graphical usage interfaces with voice recognition software.
For instance, you may have heard of Detroit Become Human (a Sony game released in 2018), which showed probably the highest level of futuristic human android assistants and voice user interface design throughout the game. I would recommend playing that game since it gives such a realistic experience, and it is a choice game, making it all the better. Your choices are based on the future events of that game! Although the game itself is not VUI itself, the gameplay does.
The effectiveness of a voice user interface largely depends on the quality of the software that recognizes human voice and extracts useful information from voice commands.
In addition to the traditional role of a UX professional, it is crucial to think of these interactions as a conversation designer. Conversational UX design knowledge, such as chatbots, can be helpful in creating engaging voice interactions beyond a simple dialogue flow between humans and machines. This way, designers can add a new dimension to the user experience.

As mentioned earlier, speech recognition is a crucial factor to consider when designing voice user interfaces. However, several other essential components of VUI design must also be carefully implemented to ensure a successful user experience.
An effective voice user interface should not only excel at automatic speech recognition but also be able to synthesize natural conversation, interpret spoken commands, and communicate messages accurately. The critical components of VUI design include:
This is the foundation of VUI. Speech recognition software takes spoken words and converts them into text that the system can understand. Accuracy is important, as users get frustrated if the system misinterprets their commands. So, its speech recognition should be very strong. (Imagine if someone is sick and their voice turns out to be a little husky. VUI will be able to recognize that as well!)
NLU goes beyond simple speech recognition. It analyzes the intent behind the spoken words, understanding the context and meaning of the user’s query. This allows the VUI to respond appropriately, even if the query is phrased in an unconventional way. This is also important since this design has to include accents from all around the world.
Once the system understands the user’s request, it needs to respond in a clear and natural-sounding voice. Text-to-speech synthesis software converts generated text into an audible response that the user can easily comprehend.
This defines the way users interact with the VUI. It determines the specific commands, prompts, and responses that the system will recognize and utilize. Ideally, the interaction model should be intuitive and align with natural conversation patterns.
A voice user interface design needs to provide feedback to users throughout the interaction. This can include audio cues like beeps or chimes or even verbal confirmations like “Okay, I understand” or “Searching for restaurants near you.” Feedback keeps users informed about the system’s actions and prevents confusion.
Even the most sophisticated systems encounter errors. A voice user interface should have robust error-handling mechanisms in place. This includes gracefully handling misunderstandings, offering corrective suggestions, or politely guiding users to rephrase their queries for better results.
As VUIs become more integrated with personal information and tasks, security becomes paramount. The VUI design should prioritize data security, safeguard user privacy, and ensure secure transactions.
A well-designed voice user interface should be accessible to a wide range of users. This includes considering factors like clarity of voice prompts, compatibility with different accents and speech impediments, and offering alternative interaction methods if necessary.
The history of voice user interface design dates back to 1984 when interactive voice response (IVR) systems were first introduced. Since then, various voice user interface design devices have been launched, and the progress made in recent years is remarkable. This includes the introduction of virtual assistants such as Google Assistant and Amazon Alexa, as well as smart speakers and TVs.
Voice user interface design technology has revolutionized our world, with our homes and offices now filled with devices that can understand and recognize voice commands, taking interactions to a whole new level. Here is a list of devices, technologies and examples that actively use the power of VUI:
