When you use Voice Match on your Google Nest or Home speaker or display, your Assistant can recognize your voice and provide personalized information based on your Google Account, including calendar events, your commute, and your day.
What happens if you remove Voice Match
- Your Google Account and voice pattern will be completely removed from this device.
- Your Assistant will no longer be able to recognize your voice.
- You'll lose the ability to get personalized info.
When you delete Voice Match for your Nest Hub Max, it'll also permanently delete Face Match for the same device, and your Assistant will no longer be able to recognize your voice or give you personal results on these devices.
