This entry explores the ramifications of this latest technology platform shift. Just as the Web precipitated the emergence of e-commerce and the smartphone enabled the explosion of social media, the advent of a voice-based interface that allows people access to, communication with, and control of most anything in our world—via the IoT. Accordingly, the objectives of this entry are threefold: review the findings of these initial, and other related articles, in the context of their relevance to the changing business/ marketing landscape defined by voice based interface (VBI) to a world connected to an Internet of Intelligent Things (IoIT); understand the technical specifications and broad-based applications of VBI will be delineated along with the ramifications occasioned by the global diffusion of the IoIT; and, explore the ramifications of this new landscape will be examined through analyses of the most prominent examples of digital assistants that are in use or development.
