Voice-controlled devices shift tech industry

After decades of screen domination, technology companies, products and, indeed, the entire tech industry, are finally starting to pivot. The target of this refocused interest? After a slow and pretty rough start with Apple's Siri several years back, the idea of voice-controlled technology devices is beginning to take hold, thanks in large part to the success of Amazon's Echo and its Alexa personal assistant. The proliferation of Alexa-enabled devices at the recent Consumer Electronics Show put an exclamation point on that development. But as cool and interesting as accurate voice recognition and simple control may be, the real impact of voice-driven computing is significantly more profound.
