Google's Local Home SDK integrates with Google Assistant and enables it to run services local to the Google Assistant rather than in the cloud. In turn, Google Assistant users experience less latency and more reliability. Now, the Local Home SDK is out of developer preview with the release of v1.0.
Amazon has empowered more location-based services through Alexa with the release of a Device Address API. The API allows for the development of Alexa skills that require location data. For instance, consider a food delivery skill. Without an address, the skill would not function accurately.
