A voice user interface (VUI) allows people to use voice input to control computers and devices. In short, it’s what enables voice experiences like the Star Trek computer and Alexa, Amazon’s voice service and the brain behind millions of devices including the Amazon Echo. Voice experiences are great when they offer a faster, easier, or more delightful way of doing things.
Today's VUIs are quickly growing smarter, learning the user’s speech patterns over time and even building their own vocabulary. With VUIs fast-evolving, voice is poised to be the next major disruption in computing.
Web services and the Internet of Things provide ready-made opportunities for voice. Sensors and readouts, for example, make for natural smart-home integrations.
Now anyone can leverage learnings from fields like automatic speech recognition (ASR), natural language understanding (NLU), and text to speech (TTS).
Existing hardware can support far-field voice input processing (FFVIP), enabling a wider range of experiences with VUIs.
Thanks to advances in machine learning, VUIs are learning and adapting to users’ speech patterns, preferences, and contexts over time.
All of these advances are driving an inflection point in voice technology. But the core driver isn’t any technology; it’s us. We welcome voice experiences because we are wired for speech.
Consider the kitchen timer. With Alexa, setting a timer is as easy as saying, “Alexa, set timer for 10 minutes.” Who would have guessed pushing a few buttons on the microwave would become the less convenient option?
Like its predecessors, VUI is quickly becoming capable and robust. With each turn of technology, it took the bold, the brave, the adventurous—the indie developer—to show us what's possible. And these visionaries are now doing the same for voice, paving the way toward fully-conversational, multi-modal interactions that extend to mobile, wearables, and even virtual reality.
