The voice-first landscape

User interfaces are constantly evolving. From the early “green screens” of mainframe computers to the TouchID, voice, and facial recognition technologies, people have always looked for easier ways to interact with and retrieve information. It should come as no surprise that more and more people are embracing voice as a preferred user interface.

The early success of Apple’s Siri played a large part in making the voice user interface (VUI) mainstream. It didn’t take long for both Amazon and Microsoft to follow with voice assistants of their own. Today, all the major technology vendors have “smart speakers” with cloud-driven digital assistants that, much like Aladdin’s genie, can answer any question you might have. Well, most questions. This is why so many experts are convinced that voice will be the dominant user experience in the next year or two. It’s also why you need to make it a part of your product development plan, right now. Spending via voice assistants is expected to grow as much as sixfold in three years for users of voice assistants.
