Dunham has developed his ventriloquism skills to a high level of proficiency, and he is able to create the illusion that his puppets are fully alive. He does this by combining a number of techniques, including:
- Lip syncing: Dunham moves his lips in time with the words that the puppets are speaking. He does this so precisely that it appears that the puppets are actually speaking.
- Hand and forearm movements: Dunham uses his hands and forearms to move the puppets' arms, legs, and heads. He does this in a way that is convincing and lifelike.
- Body language: Dunham uses his body language to convey the puppets' emotions and thoughts. He does this by leaning forward or back, changing his facial expression, and making gestures with his hands.
Dunham's ventriloquism skills are so impressive that he has fooled even the most skeptical audiences. He has performed for audiences all over the world, and he has won numerous awards for his work. He is considered to be one of the greatest ventriloquist in history.
