Family voice on Google Assistant

Google Assistant supports per-person voice recognition. Train the kid’s voice and Assistant adjusts responses, filters content, and routes purchases to the parent.

Setup

  1. Google Home app › Household › add your kid as a family member (supervised).
  2. On your kid’s phone or Nest speaker: Assistant settings › Voice Match — train their voice.
  3. Family Link controls apply to their voice use — YouTube filtering, purchase approvals, content restrictions.
  4. Disable voice purchasing: Home app › Settings › Payments — off for kid voice.
  5. Enable “Filter explicit music” under the kid’s profile.

Nest Hub / Nest Mini in kid rooms

  • Nest devices broadcast and intercom by default. Disable “Live Audio” or restrict to Home members.
  • Ambient screen on Nest Hubs shows photos, news, and recently-viewed content — check what it cycles through in a kid’s room.
  • YouTube on Nest Hub can play full YouTube or YouTube Kids. Set YouTube Kids as default.

Do Not Disturb + Downtime

Family Link’s Downtime covers the kid’s phone but not always the Nest speaker. Set Nest’s own Do Not Disturb schedule for kid rooms.

Privacy

Voice recordings are opt-in on the kid’s account. Home app › Google Account › Data & privacy › Web & App Activity › off for “Include voice and audio recordings” on the kid’s profile.
