Most people who have had an iPhone for even a short amount of time know how to work the basics of Siri. The built-in voice-controlled personal assistant is available for Apple users.
By talking to it you can ask it to do things such as making calls, texts, using apps and getting things done with just the use of your voice. According to Apple it says you can "do it all even when your hands are full".
This means it can help you stay in touch with others by asking it to text or call people, set reminders and even find where you parked your car. It promises to offer the "strongest privacy" of any intelligent assistant - but not everyone knows everything it can do.
