Amazon Echo (4th Gen) vs Google Nest Audio

The Amazon Echo (4th Gen) wins overall, with a higher owner rating, a lower price, full Zigbee/Thread hub support, and built-in sensors. The Google Nest Audio is the better choice only if your smart home already runs on Google Home.

Ecosystem and hub reach. The Amazon Echo (4th Gen) uses Alexa and is a full Zigbee/Thread/Matter hub with motion and temperature sensors, while the Google Nest Audio uses Google Assistant and only bridges Matter, with no built-in sensors.

No. The Echo (4th Gen) is Alexa-only and the Nest Audio is Google Assistant-only, so neither works with the other's voice platform, and neither supports Apple HomeKit or Samsung SmartThings. Both bridge Matter accessories.

The Google Nest Audio has a one-year warranty, while the Amazon Echo (4th Gen) has a shorter 90-day warranty. The Nest Audio also runs a local conversation agent, whereas the Echo processes speech in the cloud.

Buy the Echo (4th Gen) if you use Alexa and want a highly rated, affordable speaker that also serves as a Zigbee/Thread/Matter hub with motion and temperature sensing.

Buy the Google Nest Audio if your smart home is built around Google Home and Nest devices and you want Google Assistant, stereo pairing, and a one-year warranty.
