After using Siri regularly for a while, it soon becomes second nature to use the virtual assistant to call or text a contact in your address book.
You can ask Siri to assign relationships to your family, friends and even your boss. This means you can use more natural language to get in touch with contacts you have assigned a relationship to. For example:
Text my husband I'll be home in 30 minutes
Send an email to my boss
The first thing you need to do is teach Siri who you husband, wife, best friend or boss are, before it can assign them to a contact.
You may find you have relationships that conflict, such has having two brothers. In this case you can differentiate them by using a variation on the relationship, such as 'older brother' and 'younger brother'.
You can also add relationships the 'traditional' way by editing your contacts on your iPhone, iPad or Mac.
To remove a relationship, it needs to be deleted from the contact card.
