The best tools for developing voice user interfaces

A voice user interface, or VUI (pronounced VOO-hee), is described as a technology that allows people to interact with a computer or device using spoken commands. VUI technology is evolving much faster than its predecessors (think keyboards, mice and touchscreens). It's estimated that 94 million people own a smart speaker in the U.S. alone, and anyone who has used a mobile phone or TV remote in the last five years knows stand alone smart speakers aren't the only place where voice user interfaces are prevalent. A lot of this growth can be attributed to the technology itself. The artificial intelligence that powers the natural language understanding (NLU) behind the voice-powered experiences of giants like Apple, Amazon and Google is nothing short of amazing, but it's not just the remarkable technology that is driving the growth. Consider that we as human beings have been using spoken language for no less than 200,000 years (by most accounts).
