Alexa voice software to offer Fitbit progress updates

Alexa, what can you tell me about my health? Starting Thursday, Amazon's voice assistant will tell you how well you slept and how much more exercise you need -- at least if you have a Fitbit fitness tracker and an Alexa-compatible device, such as Amazon's Echo speaker and Fire TV streaming devices. Inc.'s answer to Apple's Siri, Google Now and Microsoft's Cortana -- is part of the online retailer's ambitions to control your living room, as people start embracing a "smart," automated home. You can already use voice commands to ask Alexa for weather, movie listings and sports scores. Ask about your sleep, and Alexa will tell you when you fell asleep and for how long.
