Why do people give their pets–and their babies–human voices–aka ventriloquating?
Deborah Tannen, a linguist at Georgetown University, did a small study on what she calls “talking the dog” in 2004. She had family members record everything they said to one another for a week, and found that when they ventriloquated (a technical term) for their dogs, they seemed to do so for one or more of several reasons: “effecting a frame shift to a humorous key, buffering criticism, delivering praise, teaching values, resolving potential conflict, and creating a family identity that includes the dogs as family members.”
