What is Voice-User Interface?

What is Voice-User Interface? User interface (UI) has drastically advanced over the years and has brought up a new form of UI known as voice-user interface (VUI). Voice User Interface is what makes the interaction between spoken human language and a computer device possible. In order to do this, the device’s interface uses speech recognition to understand questions or commands from its user.

A device that uses VUI is called a Voice Command Device (VCD). Examples of a Voice Command Device include Apple’s Siri, Amazon Alexa, and Google Home. VUI can also be found in other popular products such as automobiles, computers, smart phones, and more. These devices are voice assistants made to help people in daily tasks. Not only are there Voice Command Devices, but VUI integrated voice controlled applications that serve the same purpose as well.

Users can ask for information from the news and weather channel or simply send a voice text with the power of VUI. The benefit of devices and apps controlled by voice is that they are hands-free, so users can interact with the device while focusing on something else. This is very useful for productive multitasking in work spaces and at home. Especially as phone screens become more and more cramped with visual data, using voice unlocks a new world of workflow possibilities.

Over time, the interaction between the user and voice-user interface improves thanks to machine learning. The user learns how to better utilize the Voice Command Devices and the device in return learns how to work with its user. Thanks to these machine learning algorithms and natural voice understanding, we are working towards more natural Voice AI and a more natural user interface experience.
