Onstage at I/O 2018, Google demonstrated a new capability of Google Assistant where it can make phone calls on your behalf. CEO Sundar Pichai played back a phone call recording done by the assistant.
The assistant called a hair salon to make a haircut appointment. The voice sounded so real, if you didn't know where the phone call was coming from, you would have no idea it was the Google Assistant.
Google Assistant even dropped in a super casual “mmhmmm” early in the conversation.
Watch the video recording below.
