The actress and stand-up star, who did not name the movie she was shooting at the time, was speaking to radio DJ Howard Stern about the issue of rape in her comedy when she made the revelation.
Asked by Stern if women ever approach her and say she can't joke about the subject because she hasn't been raped, Silverman replied: "I haven't... I've had violating experiences that make me go, 'Whoa'. I never take rape lightly. I talk about the most brutal, upsetting, traumatic things and that's one of them."
When Stern asked her about being violated, Silverman said: "I've had experiences in my life... I had a brutal sex scene in something that [before] I was looking around going, 'Is there gonna be a board or something between us?'
