Ask Siri on iPhone
Talking to Siri is a quick way to get things done. Ask Siri to translate a phrase, set a timer, find a location, report on the weather, and more. The more you use Siri, the better it knows what you need.
To use Siri, iPhone must be connected to the Internet. Cellular charges may apply.
