How can I delete contact relationships in Siri?
Solution 1:
Tell Siri "My father is XYZ" and let it make the change for you.
Solution 2:
According to this Apple discussion forum, the way to modify the contact is:
- Go to Settings->General->Siri
- Tap 'My Info'
- Change the wrong profile to the correct contact
Alternately, you can also follow the instructions from this post:
Set up a contact for yourself and edit it to add a field "relationship" or something like that. Then you can add mother, brother, etc. Next time you tell siri to "send text to your mom it will know.
