siriSiri is software for the iPhone from Apple that provides the user with a personal assistant that can perform various tasks based on the user's voice commands: It can answer questions, schedule meetings, send messages, and do a number of other things that are helpful to the user. As an example, the user can say a command such as "Wake me up at 6:30 a.m.", and Siri will set an alarm to wake up the user at that time.

To activate Siri on an iPhone, press and hold the home button for two or three seconds, then release. Siri will activate and accept voice commands.
