It’s a very slow Friday in the world of mobile news, so I’ll direct your attention to this thought-provoking piece from eWeek.com that claims voice is the future of mobile user interfaces. The story points to Apple’s Siri and Microsoft’s Audible, and compares the emergence of voice-recognition technology to that of touchscreens. I think that’s a valid comparison, but I also think that voice (like touch) is just another step in the evolution of how we interact with our phones. Other UI technologies are on the horizon, and it won’t be long before voice is just one of several ways we use phones, computers and all kinds of connected devices.
