The term Voice User Interface (VUI) is a speech recognization technology that allows users to interact with a machine (like Laptop, IPad, Mobile devices, etc ) with voice commands. VUI is capable of capturing human speech with great accuracy. The development of natural speech recognition and text-to-speech synthesis has allowed the popular adoption of several voice interfaces. VUI gives a platform for more efficient interactions which are more personal than any other form of the user interface such as typing on the keyboard or clicking through the mouse since speech is the primary means of human communication. Keyboards can work for text-intensive tasks like writing a blog article, but for simple tasks like searches, post updates, adjusting controls, and getting directions, people prefer the speech-to-text convenience.

The biggest advantage of a VUI is that it allows you a hands-free, eyes-free way to interact with a product while focusing your attention elsewhere.VUI is rapidly becoming one of the most booming hand-less interfaces through devices like Google Assistant, Siri, Cortana, Google Home, Amazon Alexa, and other VUI supporting devices. Technically it’s an advanced system that uses modern and innovative technology based on machine learning and artificial intelligence, to be operated purely through voice.
