Amazon's Alexa voice assistant can now give you progress reports if you wear a Fitbit fitness tracker.
Ask about your sleep, and Alexa will tell you when you fell asleep and for how long. Ask about your daily walks, and Alexa will reply with how many more miles you need to reach your goals. Alexa might also add some encouraging words, such as "I believe in you."
Alexa works with Amazon's Echo speaker and Fire TV streaming devices. It's Amazon's answer to Apple's Siri, Google Now and Microsoft's Cortana. You can already use voice commands to ask Alexa for weather, movie listings and sports scores. In recent weeks, Alexa has also acquired such capabilities as paying Capital One bills and ordering pizza from Domino's.
