According to Strategy Analytics' WDE (Wearables) research service, global smartglasses sales are set to double from 2014 to 2015 and growth will hit 110% in 2016.

Because more conventional touch based device controls are inherently lacking on head worn wearables, Voice Recognition technology is an essential interface-control mechanism enabling hands-free control of smartglasses. Voice recognition in smartglasses, smart-goggles and smart-sunglasses will be driven by companies like Nuance, Apple, Cool Glass One and Google in the future.

WDE forecasts that Voice Recognition in smartglasses will be used to control most aspects of smartglasses device usage, surpassing a 67% penetration rate of device shipments in 2015.

Our report -- available for clients here -- can be used by hardware vendors, component suppliers, operators, software developers, content developers and other stakeholders to determine the future size and growth rate of the Voice Recognition enabled smartglasses market globally.
