Reddit users have discovered a method to access the new Gemini voices for Google Home devices before the official rollout by manually initiating the onboarding process. This workaround allows users to change their voice settings while still using Google Assistant. The upgrade introduces ten new voice options and is part of an early access program being rolled out on a per-home basis. Users can enter a specific URL to modify voice settings on their Home and Nest devices, but the full suite of Gemini features will not be accessible through this method. The longevity of this hack is uncertain, as it is unclear if Google will address it.
