Yeardley Smith has been the voice of Lisa Simpson on FOX's hit television show The Simpsons since 1987. With 700+ episodes to date, the show is currently in its 30th season and has just been renewed for a 31st and 32nd season.

Smith appeared on The Beat on 1 this week to discuss the character she's voiced for over three decades and her work on behalf of the LGBTQ community.

"Truly genuinely I never tire of talking about Lisa Simpson," said Smith. "I really do feel like she's one of the best, most fully formed female characters in any medium that we have in entertainment, and truly, I love being in the heart and soul of that little person, it's such an honor."

She also revealed a secret behind the character.

"Lisa Simpson really is the soul and the angst of all the writers in the writers room," said Smith. "They were all the smartest people in the room when they were growing up and so they were all these misfits, and so they're working all that out through Lisa Simpson."

This weekend Smith will be presented with an award from the Human Rights Campaign for her work on behalf of the LGBTQ community. 

"I'm enormously honored to be honored by the Human Rights Campaign. I've been a staunch ally of the LGBTQ community for many many, years when we were overturning Prop 8 11 years ago. I was a big part of that," said Smith. "I really feel like you cannot cherry-pick people's human rights, even if someone is different from you. You don't get to say I get to have this but you don't."

Smith also talked about her true crime podcast, Small Town Dicks, in which her and co-host Zibby Allen discuss big-time crimes happening in small towns with the actual detectives who investigate them.
