What is a Voice User Interface? In this piece, you’ll get the definition, a few voice examples, and learn about some of the best VUI devices available. With many VUI device options on the market, voice user interface design has become important. I’ll give you a few tips for that as well. 

The Switch to Voice User Interface

Each decade we have seen a new form of interaction between human and computer. If I go a little bit back in time, we were using mouse and keyboard to communicate or to talk with a computer. Then we started using touchscreen laptops and smartphones where there is no need for keyboard or mouse to interact with a device. Nowadays, laptops and computers have inbuilt VUI to communicate with a computer.

Why VUI?

Voice User Interface allows a user to interact with computer or mobile or other electronic devices through speech or voice commands. Voice or speech is an input/output for any VUI device. VUI is an interface of any speech recognition applications. Many Voice User Interface devices and voice examples are available on the market.

Amazon Alexa, Echo Dot, Google Home, Google Mini, Siri, Cortana, and the Google Assistant are the examples of VUI devices which take voice /speech as an input and returns in the same manner. People use VUI device in their daily life one or another way.

When did VUI start?

The difference between a VUI and Artificial Intelligence in general was blurred until some time ago. Factors that contributed to the field can be traced to recent advancements in speech-to-text and text-to-speech technologies, together with advancements in Natural Language Processing and cloud services as a whole. Moreover, the quick adoption of voice-only devices like Alexa and Google Home consolidated the concept. Once millions of people are able to interact with a computer with their voice, the idea of the voice being an interface – a VUI – became mainstream.

Voice Examples using the Alexa Tool 

1. The Capital One skill allows you to check your credit card balance or make a payment when one is due. This is secure: The skill performs security checks and requires you sign in using your username and password. Then, when you open the skill, you must provide a four-digit code to confirm your identity. Just be wary of who is around when using the skill — anyone who overhears you say your key can access your banking or credit card info just by asking Alexa.

2. You can use IFTTT to push additions to your Amazon To-do List to Google Calendar, or you can use the Quick Events skill. Say something like “Alexa, tell Quick Events to add go to the grocery store tomorrow at 6” to add an event to your calendar.

3. If you wear a Fitbit tracker on your wrist, you can enable the Fitbit skill. With this skill, you can ask Alexa about your progress or how you slept the night before. Before you can use the skill, however, you will need to link your Fitbit account by going to the skill page for Alexa and linking your account.

I have mentioned a few skills of Amazon Alexa here, but you can ask about the weather, education, population and many more things. You can even play games! Amazon Alexa device offers Akinator. It can read your mind and tell you what character you are thinking about, just by asking a few questions. Think of a real or fictional character and Akinator will try to guess who it is. This is one of best games offered for Amazon Alexa. If you’re interested in creating your own Alexa skill, check out our paragraph on voice user interface design below.
