Bob West

In 2000, he retired from voicing Barney and was temporarily replaced from Barney by voice actor Duncan Brannan, who met him through their affiliation, and Tim Dever. In 2002, Dean Wendt replaced Brannan and Dever as the purple dinosaur's voice and Carey Stinson replaced David Joyner as the character's body performer. However, West's pre-recorded voice can still be heard in A Day in the Park with Barney at Universal Studios Florida, as it was recorded in the mid 1990s and his archival recordings are still heard in some of HIT Entertainment's The Little Big Club live stage shows. West also reprised the voice for Barney in 2005 during the PBS Kids Sprout Launch.

West became the voice of Barney in 1988, his first voice work as Barney was for the direct-to-video series Barney and the Backyard Gang. He went on and continued voicing Barney in the television series Barney & Friends and would reprise the role again in a 70 market radio show, on Multi-Platinum and Multi-Gold albums, Barney's Great Adventure, for CBS and NBC primetime specials, for touring performances, as a Daytime Emmy presenter, for toys, for educational games, and for "personal appearances". He also voiced interviews on The Today Show, LIVE! with Regis & Kathie Lee, Oprah, The Donahue Show, John & Leeza From Hollywood, Marilu, and appearances around the world.

West's first voice over job were the characters Jasper T. Jowls and Pasqually in the Chuck E. Cheese's animatronic stage show from 1986 to 1998.
