Siri is certainly smart, but she’s not a mind reader—if you want to be able to tell her to call your mom, you have to tell Siri who she is first. Doing so is amazingly simple. Just call up Siri, and when you hear the familiar prompt, say “Jane Doe is my mother” or “John Doe is my father”—note that you should use your actual family member’s names, unless your name happens to be James Doe—and soon enough Siri will know your spouse, parents, siblings, and other relations—possibly better than you do.
