Great ear for the nuances of human speech and dialects. He has performed a number of voice roles for historical TV documentaries including Abraham Lincoln, Thomas Jefferson, and Pilgrim William Bradford, first governor of Plymouth.
Once asked: "How do you create a compelling voice for a character whose voice was never recorded?"
He answered: "I start with historical research, trying to understand the size, shape, and temperament of the person. Then I try to estimate what sound - if any - might already be in the mind of the audience, something from a movie or TV show. Sometimes, I'll try to approximate that - or I might take it in a different direction.
For example, Jefferson. While he was English by heritage, he was born in Virginia. He was a slender man, so I couldn't imagine him with a deep, ponderous voice. He was comfortable with words - a brilliant writer and an inventor. That suggests the traits of curiosity, a lively speaking voice, and a sense of humor. So I made his voice lighter, cultured, and slightly English with a Virginia lilt."
Appreciating a good-natured challenge, Robert has also created a host of cartoon character voices. If you have a specific voice in mind, let Robert's imagination take you for a ride.
