Google Duplex AI Revolutionizes Phone Calls with Autonomous Virtual Assistant
Today (06/06/2026), Google announced the official launch of Duplex AI, an artificial intelligence-based voice system that can make phone calls and complete tasks such as restaurant reservations, salon appointments, and medical consultations without human intervention.
The novelty was presented during the annual Google I/O conference, taking place this week in Mountain View, California. According to the company, Duplex AI can hold natural conversations with human interlocutors, adapting its tone, pauses, and intonation to sound like a real person.
How does it work?
The system uses a recursive neural network architecture trained on millions of anonymous phone conversations. Unlike common assistants, Duplex AI can handle unexpected situations: if the restaurant is full, it asks for alternative times; if the salon doesn't offer the desired service, it suggests similar options.
Google states that the technology is already being tested in partnership with over 700 establishments in the United States and Canada. The result? In 85% of cases, the person on the other end did not realize they were talking to a robot.
Privacy and Security
Despite the enthusiasm, experts raise questions about privacy. Duplex AI records calls for continuous learning, but Google ensures that all data is encrypted and anonymized. Users can access the full history of interactions and delete it at any time in their Google account settings.
Additionally, the company implemented a consent system: before any automated call, Duplex AI identifies itself as "Google's virtual assistant" and asks if the person agrees to continue. If the interlocutor refuses, the call is immediately terminated.
Availability
Google Duplex AI will initially be available for Android and iOS smartphones in the US and Canada starting in July 2026. Other countries should gradually receive the feature by the end of the year. Integration with Google Assistant will allow users to simply say: "Ok Google, book a haircut for tomorrow at 10 am," and the AI handles the rest.
Impact
The news has sparked debates among digital ethics experts. Dr. Carlos Menezes, AI professor at USP, commented: "It's an impressive advance, but we need to discuss the impact on telemarketing and secretarial jobs. The replacement could be fast and chaotic."
Meanwhile, the restaurant sector celebrates. Maria Silva, owner of a bistro in São Paulo, tested the system in beta: "It reduced by 60% the time I spent on the phone. Now my employees focus on in-person service."
Google says it plans to expand Duplex AI to other sectors, such as healthcare and education, in the coming months. In the meantime, the world watches with curiosity and caution a new era in human-machine interaction.
