Siri is a Scandinavian short form of Sigrid — from the Old Norse sigr ("victory") + fríðr ("beautiful"). Apple's Siri — the voice-controlled intelligent personal assistant launched October 4, 2011 with iPhone 4S; one of the most-recognized AI products in consumer history, with over 1 billion active devices using it as of 2024; named after a co-founder's coworker and from the Old Norse meaning; voiced originally by Susan Bennett (2011-2013). Siri Hustvedt (born 1955) — American novelist and essayist; The Blazing World (2014) longlisted for the Man Booker Prize; The Summer Without Men (2011) bestseller; married to author Paul Auster; one of the most-respected American literary voices of the 21st century. Siri Tollerød (born 1989) — Norwegian model. Siri Lindley — American triathlete; two-time ITU Triathlon World Cup champion. Siri Pinter — wife of Carson Daly. The original "Siri" is the lake in Norway from which the name derives. The name's surge after 2011 is among the most-documented cases of brand-influenced naming in modern US statistics.
