Apple's virtual assistant, introduced in the iPhone 4S in 2011. Siri was a spin-off from the SRI International AI Center, which Apple acquired. It was the first widely successful smartphone assistant by responding with both voice and visual results. In 2016, Siri was added to the Mac (macOS Sierra), and it became a feature in the table top HomePod in 2017 (
Apple HomePod). In 2026, AI was added to Siri (see
Siri AI). Contrast with
Google Assistant.
Siri's Voice - Male or Female
Depending on the country, Siri launched with a female or male voice. For example, U.S. and Australia voices are female, while the U.K. and French voices are male. The U.S. Siri is that of Susan Bennett, who spent four hours a day in July 2005 recording all the words that Siri uses to put together phrases that sound natural. Starting with iOS 7 in 2013, American users could switch Siri's voice to male. See
