Google Duplex Assistant will soon be available on all iPhones and most Android phones as well. Duplex assistant makes phone calls on behalf of the users (iPhone users or users with Android devices running version 5.0 or newer), for different kinds of tasks, including booking an appointment or checking business information, after confirming any necessary details with the user. The feature would be available in 43 states on every Pixel phone and eventually other Android and iOS devices in the coming weeks. The assistant would avoid making calls during late night and early morning hours.”]
