Who is the voice of the character Lisa Simpson?

Yeardley Smith born Martha Maria Yeardley Smith; July 3, 1964) is a French–American actress, voice actress, writer, comedian, and painter. She is best known for her long-running role as Lisa Simpson on the animated television series The Simpsons.

She was born in Paris and moved with her family to Washington, DC, in 1966. As a child, Smith was often teased because of her voice. She became a professional actress in 1982 after graduating from drama school and moved to New York City in 1984, where she appeared in the Broadway production of Tom Stoppard's The Real Thing. In 1987, she auditioned for a role in a series of animated shorts about the Simpson family on The Tracey Ullman Show. Smith intended to audition for the role of Bart Simpson, but the casting director felt her voice was too high, so she was assigned the role of Lisa, instead. She voiced Lisa for three seasons on The Tracey Ullman Show, and in 1989, the shorts were spun off into their own half-hour show, The Simpsons. For her work as the character, Smith received a Primetime Emmy Award for Outstanding Voice-Over Performance in 1992.
