  "country": "US",
  "title": "How Sonos Speakers Use Personalized Wake Words to Recognize Different Users",
  "original_title": "Voice controlled media playback system based on user profile",
  "summary": "A system that lets multiple people control a shared speaker by using unique voice-trigger words to link their specific music accounts and preferences.",
  "what_it_does": "This patent describes a way for a smart speaker to distinguish between different people in a home by assigning each person a unique 'wakeup word.' When a user speaks their specific word, the system identifies their linked user profile and music service account. It then executes commands—like playing a playlist or adjusting volume—using that specific person's settings and account history. For example, if you say 'Alexa, play jazz' and your partner says 'Hey Sonos, play rock,' the system knows exactly which music account to pull from based on the unique trigger word used.",
  "what_it_does_not_cover": [
    "Does not cover voice recognition based on biometric voice printing or vocal characteristics.",
    "Does not cover systems that rely on a single, universal wake word for all users.",
    "Does not cover controlling media devices that are not connected to a remote music service account."
