In the Alvin and the Chipmunks (film)|2007 CGI/live-action movie adaptation]] and its Alvin and the Chipmunks: The Squeakquel|2009 sequel]], they were voiced in dialogue by Justin Long]], Matthew Gray Gubler]] and Jesse McCartney]]. After the death of Bagdasarian in 1972, the characters' voices were performed by his son Ross Bagdasarian, Jr.]] and the latter's wife Janice Karman]] in the subsequent incarnations of the 1980s and 1990s. Bagdasarian, performing as the Chipmunks, released a long line of albums and singles, with "The Chipmunk Song (Christmas Don't Be Late)|The Chipmunk Song]]" becoming a number-one single in the United States.

This oft-used process was not entirely new to Bagdasarian, who had also used it for two previous novelty songs, including "Witch Doctor (song)|Witch Doctor]]", but it was so unusual and well-executed it earned the record two Grammy Award]]s for engineering. The voices of the group were all performed by Bagdasarian, who sped up the playback to create high-pitched voices. The characters became a success, and the singing Chipmunks and their manager were given life in several animated cartoon]] productions, using redrawn, anthropomorphic chipmunks, and eventually films. In reality, "David Seville" was Bagdasarian's stage name, and the Chipmunks themselves are named after the executives of their original record label. The trio is managed by their human adoptive father, David (Dave) Seville. The group consists of three singing animated anthropomorphic chipmunk]]s: Alvin, the mischievous troublemaker, who quickly became the star of the group Simon, the tall, Glasses|bespectacled]] intellectual and Theodore, the chubby, impressionable one. Alvin and the Chipmunks is an American Virtual band|animated music group]] created by Ross Bagdasarian, Sr.]], for a novelty record]] in 1958.
