Siri lets you speak to iPhone/iPad and you can get things done just by asking for them. Siri understands natural speech, you don´t have to learn special commands or keywords.
NOTE! To use Siri, iPhone/iPad must be connected to the Internet.
To use Siri, go to Settings> Siri and search> do the following settings:
Listen for “Hi Siri”
Press the Home button for Siri
Allow Siri when the screen is locked
Choose language, Siri voice, voice feedback and give her information about you.
Tell Siri about yourself – for example, your home address and work address and your relationships – then you can get personalized service like, “remind me to call my husband when I get home. “Tell Siri who you are. Fill in your details in Contacts. To let Siri know about a relationship, say something like “Bill Clevenrot is my husband.”
Press and hold the Home button and say “Hi Siri,” until Siri beeps. Control when Siri listens. Instead of letting Siri notice when you stop talking, you can continue to hold down the Home button while you speak, then release it when you finish. Hey Siri.
With iPhone/iPad connected to a power source or if you have already started a conversation with Siri, you can use Siri without even pressing the Home button. Just say “Hey Siri,” then make your request. If you are using a headset, you can use the center or call button in place of the Home button.
Ask her to call Face Time calls to someone in your contacts, open email programs and write a letter to someone you have in your contacts. Ask her to put the alarm clock, remind you of an activity, etc.
For hints, ask Siri “what can you do”. Depending on your request, the onscreen response from Siri often includes information or images that you can tap for additional detail or to perform some other action like searching the web or opening a related app.
