Both Alexa and Google Home can make phone calls, but the specific features and capabilities may vary. Alexa allows you to make voice calls to other Alexa devices or even regular phone numbers using compatible Echo devices. Google Home, on the other hand, offers voice calling through Google Duo, allowing you to make calls to other Google Duo users or phone numbers in supported countries. Checking the device’s specifications will provide you with a better understanding of the calling capabilities available.
