It is believed there are/were several actors involved, common with costumed animal characters.
Barney is technically not fake, because a person used to play Barney, but he is just a main character in a show. Barney may be based on a real animal[not sure which]. Barney seems to just be a person with a weird voice, dressed in a giant costume. No actual talking animals could ever not fake. Hope that answers your question.
