Tell Siri about yourself on iPhone
If you tell Siri about yourself—including things like your home and work addresses, and your relationships—you can get personalized service so you can say things like “Send a message to my husband” and “FaceTime mom.”
Tell Siri who you are
Open Contacts , then fill out your contact information.
Go to Settings > Siri & Search > My Information, then tap your name.
Tell Siri how to say your name
Ask Siri. Say something like: “Learn to pronounce my name.”
Tell Siri about a relationship
Ask Siri. Say something like: “Eliza Block is my wife” or “Ashley Kamin is my mom.”
Keep what Siri knows about you up to date on your Apple devices
On each device, go to Settings , then sign in to iCloud with the same Apple ID.
Your personal information is encrypted and remains private.
To prevent Siri information from being updated between iPhone and your other devices, go to Settings > [your name] > iCloud, then turn off Siri.
Note: Siri uses Location Services when your requests require knowing your location. See Set which apps know your location on iPhone.
