When you press and hold the Home button on iPad, iPhone, iPod touch, Siri asks, “What can I help you with?” Tap the “i” button to see a detailed list of the ways Siri can help you get things done.
Tell Siri about your relationships, such as “Lisa Gee is my
wife” or “Albert is my dad.” Then you can say “Text my wife” or “Call dad” and
Siri knows who you mean.
Be sure to enter your home and work addresses in Contacts.
That way, Siri can remind you to do things when you leave or arrive at either
place.
You can dictate a quick response to an email. Just say
"Reply," then tell Siri your message.
