Amazon will unveil eight new Alexa-powered devices for the car and home before the end of the year, according to a report. They include a microwave oven, an amplifier, a receiver, a subwoofer and an in-car gadget. Amazon is expected to reveal some of the devices at an event later this month. All the devices will connect easily to Alexa, and some will have the voice assistant built in. The products mark Amazon's first move into the home appliances market, an area where competitors have already staked out their turf.
