Amazon's Echo speaker gets a touch screen and video calling

Amazon is giving its voice-enabled Echo speaker a touch screen and video-calling capabilities as it competes with Google's efforts at bringing "smarts" to the home. The 7-inch screen on the new Echo Show enables the speaker to supplement voice responses with visuals and other information displays, similar to the Echo-like features offered on the Fire tablets and Fire TV streaming devices. That could mean extended weather forecasts, not just current conditions. It could mean lyrics to go with the song you're listening to. You also could call up cooking tutorials on YouTube, hands-free, while making dinner in the kitchen.
