A ventriloquist is a PERFORMER who uses the art of ventriloquism to create the illusion that their puppet is speaking without them moving their lips. Ventriloquism is an ancient art form that dates back to ancient Greece and Rome, and has been used in entertainment for centuries. The ventriloquist is able to manipulate their voice to make it sound like it is coming from the puppet, and can also use facial expressions and body language to add to the illusion.
