(Bloomberg) -- As Amazon.com Inc. and Google work to place their smart speakers at the center of the internet-connected home, both technology giants are expanding the amount of data they gather about customers who use their voice software to control other gadgets.
For several years, Amazon and Google have collected data every time someone used a smart speaker to turn on a light or lock a door. Now they’re asking smart-home gadget makers such as Logitech and Hunter Fan Co. to send a continuous stream of information.
