What is a Voice User Interface?
A Voice User Interface(VUI) enables users to interact with a device or application using spoken voice commands. VUIs give users complete control of technology hands free, often times without even having to look at the device. A combination of Artificial Intelligence(AI) technologies are used to build VUIs, including Automatic Speech Recognition, Name Entity Recognition, and Speech Synthesis among others. VUIs can be contained either in devices or inside of applications. The backend infrastructure, including AI technologies used to create the VUI’s speech components, are often stored in a public or private cloud where the user’s speech is processed. In the cloud, AI components determine the intent of the user and return a given response back to the device or application where the user is interacting with the VUI.

Well known VUIs include Amazon Alexa, Apple Siri, Google Assistant, Samsung Bixby, Yandex Alisa, and Microsoft Cortana. For the best user experience, VUIs have visuals and additional sound effects to accompany them so that users know when the VUI is active, listening, processing speech, or responding back to the user. VUIs today have different ways of handling this. Benefits of VUIs include hands-free accessibility, productivity, and better customer experience.
