In this article, you can find some great tricks and tips on designing a great voice interface. Sounds scary? After the read, you’ll get your courage back!
Human-to-human communication is said to be very complicated. There are many languages, dialects, spelling differences, intonations, and of course – interpretations, so sometimes we have to concentrate very hard to understand what someone else is saying, and the thing that allows us to do so is our intelligence combined with intuition.
But in the 21st century, we communicate not only with other people but also with electronic devices. Artificial intelligence and machine learning are at a very advanced level these days. However, there’s still a lack of intuition here, so voice experience designers have a tough nut to crack when creating a user-friendly journey for IoT (Internet Of Things) devices.
The Google Home smart speaker user base expanded by 7.2 million in the U.S. in 2018, according to data compiled as part of the 2019 U.S. Smart Speaker Consumer Adoption Report. That reflects a rise of 600,000 more new Google Home users than Amazon Echo added in 2018.
According to my observation, many people think designing voice experiences is a completely different thing than creating graphical user interfaces. If you’re among them, you’re wrong! Designing voice-based experiences are said to be a new direction of UX design, but it’s definitely not – it’s just a next step that happens naturally. Even more – it’s a great idea to adapt the visual design experience process (e.g. 10 Usability Heuristics for User Interface Design from 1994) for creating voice-based devices.
Here are some precious tips for creating a winning voice user interface – let me know if they helped you!
Similar to every digital product, you need to apply user-first design when creating a voice-based experience. That’s why user research is CRUCIAL here. Its goal is to understand the target user’s needs and behaviors, and gathered information would be the product’s foundation. To develop your personas, you should ask yourself who would use this app and how it would help solve their problems most quickly and effectively.
After establishing some perfectly-crafted personas, you need to focus on:
To get a full understanding of voice-based systems, you can also buy or borrow a smart speaker and test it like there’s no tomorrow. It’s always a great idea to try different voice apps and check how other voice interface designers approached the problem. Find the best examples and analyze them step by step, writing down every inspiring solution – you never know when you’ll need some quick inspiration.
In this step, you have to shape the future product and define all of its capabilities.
Now your main goal is to design scenarios that will have the highest value for your target users. First of all, you need to figure out which of the 4 possible voice input triggers will be relevant in your case.
The voice input triggers:
When kicking off projects involving visual interfaces, most designers’ first step is a whiteboard to sketch out some raw concepts of the user experience. But what if your product doesn’t have a screen? Just create simple scenarios by writing down a basic back and forth conversation between the user and the voice app.
Don’t forget to answer additional questions, eg. Will users know what they want to do, or should you offer some options? What will users say to start the app? What the tone and personality of the voice experience will sound like? And if you feel you’re stuck, ask yourself – how would you design if it was a visual user interface? Then try to translate it into voice.
After designing the scenarios, you have to make sure they perfectly work with voice.
Remember that the project’s ultimate goal is to provide users with the ability to solve the problem way faster than using any alternative experiences. Keep the scenarios short because selecting from a long menu is very difficult with voice interactions.
Btw. don’t forget to prepare the error scenarios! Users will likely speak too fast, too slow, too quiet, etc., etc., and you have to be prepared. Make sure your scenario involves a request for repeating the voice command, e.g. Say it again?
Another thing is that some users will get confused and could use some navigation through the experience. For example:
Voice-based device: What’s your date of birth?
User: Ummm…
Voce-based device: Jason, please tell me your date of birth using 2 digits for the month, 2 digits for the day, and 2 for the year.
It’s time to face the public.
Yes, now!
No, it’s not too soon. You have to test the experience before creating it and even building the prototype. It only takes a group of people who match your target users and a person playing the artificial intelligence experience you designed. Check every possible iteration with your people, write down every moment of hesitation, lack of desired option, etc. After this, interview your users and ask them to rate the experience.
Now you have all the knowledge to make some changes.
Now it’s time to let the other team members do some work. Time to build this freakin’ device from scratch and give it to the people!
Now your role is to keep your finger on the pulse and test because some issues like getting out of their caves at the final stage – you know how it is!
After rolling out your app, you need to start tracking its performance among the target group.
Some key metrics to keep your eye on every day:
Tracking these metrics regularly will help you to provide an excellent voice-based experience since you’ll be able to catch the source of the problem and redesign the process quickly and effectively.
Voice assistants are quickly becoming a common part of our daily lives – according to a survey run by Adobe, 76 percent of smart speaker owners increased their usage of voice-enabled devices over the last year. It should be crucial for designers to create voice-based experiences based more on human2human than human2machine communication style by knowing who and why they design for.
