Google Home's app on Android is rolling out a Public Preview test called "Voice Assistant," which allows users to control access to the experimental AI feature, Gemini, on their smart home devices. Gemini was first tested on Nest devices last December and is now being integrated into Google Home with improved AI-generated automations and new features. The "Voice Assistant" experiment enables users to manage how household members can access Assistant experiments, but requires "Voice Match" setup for access. Gemini enhances the Assistant's capabilities by providing more comprehensive answers and allowing follow-up questions. At the I/O 2025 event, Google announced additional features for Google Home, including a "Home Summary" widget for Pixel devices and improvements to the "help me create" feature for automation.
