Even telecom giants can't resist the temptation to hop on the smart speaker bandwagon... or can they? CNBC sources say the news site's parent company, Comcast, is developing a smart speaker focused on health. You wouldn't use this to turn on the lights or perform other smart home tasks -- instead, it would use sensors to detect trips to the washroom, long sleeping hours and falls. You could also use it to make emergency calls. Comcast confirmed to Engadget that it's working on a device, but the company says the technology is solely a sensor to detect motion, not a gadget that's built to function as a smart speaker. Comcast also says there's no function for the device beyond health.
