A: Disney has generally not publicized the actors whose voices have been used in the park attractions, though some of the Haunted Mansion actors have indeed become well-known: Paul Frees, Thurl Ravenscroft, and Eleanor Audley, to name three. Royal Dano provided the voice of Abraham Lincoln for attractions at the Walt Disney World Magic Kingdom and Disneyland park.  Pete Renoudet has done voices for a number of attractions. You can find websites that list other Disney park voices.
