Grounded, predictive, pragmatic:  Why voice is the next big thing in technology, as big as mobile a decade ago and the internet in the late 90s, fundamentally altering the way companies do business.

Tobias Dengel is in the vanguard of this breakthrough, understanding the deep, wide-ranging implications voice will have for every industry. And here he connects the dots about this emerging paradigm to vividly illustrate how business leaders can stay ahead of the game, rather than scrambling to catch up, as voice technology gradually reveals its power, creating a host of new winners and losers.
